In this study, a vacuum-assisted filtration process was employed to fabricate ammoniated alumina/MXene/bacterial cellulose (Al_(2)O_(3)-NH_(2)/MXene/BC) composite films that display a unique integration of properties, encompassing ultra-high thermal conductivity (λ), mechanical flexibility, and high photothermal conversion performance. By leveraging the bridging effect among spherical Al_(2)O_(3)-NH_(2) and MXene nanosheets, a densely packed “point-surface” structure was constructed in BC by using a one-step preparation process. When the mass fraction of Al_(2)O_(3)-NH_(2)/MXene (1:3, w/w) is 40 wt%, the O-BAl1M3 exhibited an in-plane λ of 20.02 W m^(-1) K^(-1), which was 436 % and 94 % higher than that of pure BC and T-BAl1M3 (prepared by a two-step method), respectively. Furthermore, constructing an intact thermal conductive network within BC notably promoted photothermal and photoelectric conversion performance. The maximum surface temperature and voltage of the O-BAl1M3 film reached 106.9 ℃ and 48.34 mV when a sample with an area of 1.56 cm^(2) was exposed under a light intensity of 200 mW cm^(-2). By applying O-BAl1M3 film, the temperature inside a self-built greenhouse model reached up to 64.8 ℃ within 1200 s under a light intensity of 100 mW cm^(-2), which validated the practical application of the composite films and offered a novel approach for creating flexible films with superior photothermal conversion capability. This work provided insights into preparing functional composite films for efficient thermal management and photothermal conversion applications.展开更多

文摘With the continuous advancement of communication technology,the escalating demand for electromagnetic shielding interference(EMI)materials with multifunctional and wideband EMI performance has become urgent.Controlling the electrical and magnetic components and designing the EMI material structure have attracted extensive interest,but remain a huge challenge.Herein,we reported the alternating electromagnetic structure composite films composed of hollow metal-organic frameworks/layered MXene/nanocellulose(HMN)by alternating vacuum-assisted filtration process.The HMN composite films exhibit excellent EMI shielding effectiveness performance in the GHz frequency(66.8 dB at Kaband)and THz frequency(114.6 dB at 0.1-4.0 THz).Besides,the HMN composite films also exhibit a high reflection loss of 39.7 dB at 0.7 THz with an effective absorption bandwidth up to 2.1 THz.Moreover,HMN composite films show remarkable photothermal conversion performance,which can reach 104.6℃under 2.0 Sun and 235.4℃under 0.8 W cm^(−2),respectively.The unique micro-and macrostructural design structures will absorb more incident electromagnetic waves via interfacial polarization/multiple scattering and produce more heat energy via the local surface plasmon resonance effect.These features make the HMN composite film a promising candidate for advanced EMI devices for future 6G communication and the protection of electronic equipment in cold environments.

文摘Low photothermal conversion efficiency restricts the antibacterial application of photothermal materials.In this work,two-dimensional carbon nanosheets(2D C)were prepared and decorated with Cu nanoparticles(2D C/Cu)by using a simple soluble salt template method combined with ultrasonic exfoliation.The photothermal conversion efficiency of 2 D C/Cu system can be optimized by changing the content of Cu nanoparticles,where the 2D C/Cu2 showed the best photothermal conversion efficiency(á)of 65.05%under 808 nm near-infrared light irradiation.In addition,the photothermal performance can affect the release behavior of Cu ions.This superior photothermal property combined with released Cu ions can endow this 2D hybrid material with highly efficient antibacterial efficacy of 99.97%±0.01%,99.96%±0.01%,99.97%±0.01%against Escherichia coli,Staphylococcus aureus,and methicillin-resistant Staphylococcus aureus,respectively,because of the synergetic effect of photothermy and ion release.In addition,this 2D hybrid system exhibited good cytocompatibility.Hence,this study provides a novel strategy to enhance the photothermal performance of 2D materials and thus will be beneficial for development of antibiotics-free antibacterial materials with safe and highly efficient bactericidal activity.

文摘MXene-based composite films are regarded as up-and-coming multifunctional electromagnetic interference(EMI)shielding materials.However,the conflict between strong mechanical properties and high electrical conductivity hinders their application in modern integrated electronics.Herein,in virtue of density-induced sedimentation,robust and multifunctional liquid metals-reinforced cellulose nanofibers(CNF)/MXene(LMs-CNF/MXene)composite films with Janus structure are fabricated by one-step vacuum-assisted filtration method.Not only does the nacre-like structure of the CNF/MXene layer not destroy,but the deposited liquid metals(LMs)layer can serve as conductive potentiation.Due to the special Janus structure,an“absorption-reflection-reabsorption”shielding process is created in LMs-CNF/MXene composite film to strengthen EMI shielding performance.Its shielding effectiveness can reach 51.9 dB at -27μm,and the reflection coefficient falls to 0.89,below those of reported MXene-based shielding films.Meanwhile,the CNF/MXene layer can endow composite films with excellent mechanical properties with a super tensile strength of 110.3 MPa.Notably,the LMs-CNF/MXene EMI shielding composite films also integrate outstanding photo-/electrothermal conversion performances,which can effectively deice outdoors.The robust LMs-CNF/MXene EMI shielding composite films with satisfying photo-/electrothermal performances have extensive application prospects,such as aerospace,wearable electronics,and portable electronics.

文摘Charge-transfer(CT)stoichiometric cocrystals are promising choice of organic materials for unveiling the structure-property relationship.However,due to the contradiction between large CT degree required for strong NIR absorption and flexible molecular stacking,construction of stoichiomorphism-based cocystals with near-infrared(NIR)photothermal property remains challenging.Herein,the first example of stoichiomorphism-based photothermal cocrystals were accomplished through the adaptive assembly of 3,3,5,5-tetramethylbenzidine(TMB)donor and 1,2,4,5-tetracyanobenzene(TCNB)acceptor.The selective cocrystallization could be controlled by varying the donor-acceptor stoichiometries via a surfactantassisted method,resulting in two cocrystals with 1:1(T1C1)and 1:2(T2C1)stoichiometries.The absorbance intensity of T1C1 at 808 nm was nearly twice that of T2C1,while the photothermal conversion efficiency(PCE)of the former was 60.3%±0.6%,approximately 80%of that for the latter(75.5%±2.6%),which might be caused by the different intermolecular interactions in distinct molecular stacking patterns.Notably,both excellent PCEs of stoichiometric cocrystals were attributed to the nonradiative transition process,including internal conversion and charge dissociation processes,as elucidated by femtosecond transient absorption spectroscopy measurements.Furthermore,T1C1 was used as an NIR heater for preparing agarose-based photothermal hydrogel,showing great potential for light-controlled in-situ gelation.This strategy of balancing the CT degree and molecular packing orientation not only uncovered the relationship between stoichiometric stacking and photothermal property,but also provided an opportunity to develop advanced organic optoelectronic materials.

文摘The liquid leakage and weak solar absorption capacity of organic phase change materials(PCMs)seriously hinder the efficient utilization of solar energy and thermal energy storage.To address these issues,we prepared nanoporous metal organic framework(Ni-MOF)for the vacuum infiltration of paraffin wax(PW),followed by the coating of solar-absorbing functional polydopamine(PDA)on the surface of PW@MOF for photothermal conversion and storage.As an efficient photon harvester,PDA coating endows PW@MOF/PDA composite PCMs with excellent photothermal conversion and storage properties due to the robust broadband solar absorption capability in the UV–vis region.Resultantly,our prepared PW@MOF/PDA composite PCMs exhibit a high photothermal conversion and storage efficiency of 91.2%,while that of PW@MOF composite PCMs is only zero.In addition,PW@MOF/PDA composite PCMs also exhibit excellent thermal stability,shape stability,energy storage stability,and photothermal conversion stability.More importantly,this coating strategy is universal by integrating different MOFs and solar absorbers,showing the potential to accelerate the major breakthroughs of high-efficiency MOF-based photothermal composite PCMs in solar energy utilization.

文摘Realizing precise temperature regulation under low constant near-infrared(NIR)laser density is of great significance for the clinical application of photothermal therapy.However,photo-modulated photothermal conversion materials are still in their infancy,and it is challenging and vital to develop photochromic materials with extraordinary radical stability to realize tunable photothermal conversion under an acceptable NIR laser density.In this work,we present a UV-induced photochromic inorganic-organic complex(NEU20)bearing dense packing mode of 4,4′-bipyridine(bpy)/deprotonated 4,4′-bipyridine(H_(2)bpy^(2+))dications and the unique sandwichπ-aggregates consisting of infinite H_(2)bpy^(2+)-bpy-H_(2)bpy^(2+)interaction,which can generate tunable and stable H_(2)bpy^(˙+)radicals through the UV-induced photoinduced electron transfer(PIET)process and cause absorption bands in the red and IR regions,thus modulating the NIR photothermal effect under a low constant NIR laser density.NEU20 enables precise control of photothermal temperatures through UV exposure duration besides changing the NIR laser power,and its photothermal conversion exhibits good recyclability,a high conversion efficiency and high temperature increase rate.The clear and adjusted imaging performance based on the photothermal effect is also presented.

文摘We report the synthesis,crystal structure,optical properties,and photothermal conversion properties of an ultra-stable cuprous Cu_(12) cluster,namely{[Cu_(3)^(I)(HTC_(4)A)]_(2)[Cu_(6)^(I)(2-PyS)_(6)]}·H_(2)O(Cu_(12),H_(4)TC_(4)A=p-tertbutylthiacalix[4]arene,2-PySH=2-pyridinethiol),which was built from a pre-synthesized Cu_(6)^(I)(2-PyS)_(6)(Cu_(6))precursor and two Cu_(3)^(I)-HTC_(4)A polynuclear secondary building units(PSBUs).The Cu_(12) cluster features a sandwich-like framework in which the Cu_(6) core is double surface capped by forming six Cu-S bonds with two Cu_(3)^(I)-HTC_(4)A PSBUs.The“cluster-cluster”assembly strategy enables all the metal centers in the Cu_(12) cluster to be monovalent and efficient organic ligand protection makes the cuprous cluster stable in common solvents(alcohol,acetonitrile,acetone,CHCl_(3),N N-dimethylacetamide,etc.)as well as in strong acids(pH=1)or bases(pH=14).Band gap determination and photophysical analysis combined with density functional theory(DFT)calculations indicated that Cu_(3)^(I)-HTC_(4)A PSBUs can tune the electron and hole distribution of the Cu_(6) core,which makes Cu_(12) a stable and efficient photothermal conversion material both in the solid state and in water/N,N-dimethylformamide solvents.

文摘Although the photothermal conversion properties of various self-assembled ensembles based onπ-πstacking interactions have been reported,the impact of different stacking modes on their photothermal conversion efficiency has rarely been investigated.In this study,three similar flexible pyridine ligands were assembled with the binuclear Cp*Rh building block B1,leading to the formation of three[2]-catenanes in trapezoidal metallacycles with L-B-B-L,L-L-B-B and B-L-L-B stacks.We demonstrated that theπ-πstacking modes of the building blocks can be controlled by adjusting the length and flexibility of the linkers.Comparative research studies of the NIR photothermal conversion efficiencies(57.0-83.7%)of the three[2]-catenanes indicated that the conversion efficiencies of the[2]-catenanes depend on the stacking modes of the building blocks and that the[2]-catenane with the L-B-B-L stack exhibited the best photothermal conversion ability.This research emphasizes the significance of stacking modes and presents a new approach for creating valuable NIR photothermal conversion materials based on half-sandwich metal structures.

文摘The selective hydrogenation of nitroaromatic compounds to produce phenylamines plays a crucial role in various industrial processes.Here,we introduce a Cu-MoO_(2)@C catalyst,which is synthesized by pyrolyzing a polyoxometalate-based metal-organic framework(POMOF),exhibiting remarkable catalytic efficiency in the selective hydrogenation of nitroaromatics.Specifically,nearly 100%conversion and 97%selectivity in hydrogenation of 4-nitrostyrene(4-NS)to 4-aminostyrene(4-AS)were achieved over the Cu-MoO_(2)@C catalyst under light irradiation.This promoted yield of 4-AS is ascribed to the plasmonic photothermal effect of Cu nanoparticles(NPs),which facilitate efficient photothermal conversion,as well as the strong electronic interactions at Cu/MoO_(2) interfaces,which facilitate the selective reduction of the N≡O bond while minimizing the reduction of the C≡C bond.Furthermore,the Cu-MoO_(2)@C catalyst demonstrates outstanding stability,maintaining high catalytic activity over eight cycles with minimal performance degradation.Its versatility was evidenced by the effective hydrogenation of a variety of nitroaromatic substrates containing different reducible functional groups.This study underscores the potential of Cu-MoO_(2)@C as an efficient,stable,and adaptable catalyst for the selective hydrogenation of nitroaromatic compounds,presenting a promising solution for industrial applications.
