摘要
为有效杀灭纺织物表面的耐药菌,在普通涤纶、棉布表面原位合成ZIF-67纳米颗粒,以制备出改性涤纶(ZIF-67@Dacron)、改性棉布(ZIF-67@Cotton)。通过X射线衍射、傅里叶变换红外光谱、场发射扫描电子显微镜对所得改性织物进行表征,并测试了其光热性能及抗菌能力。结果表明:ZIF-67纳米颗粒成功生长到涤纶、棉布表面。使用近红外光照射30 s,ZIF-67@Dacron、ZIF-67@Cotton表面温度分别可升至95、120℃,且这一光热特性在5次升-降温循环中保持稳定。这两类改性织物优异、稳定的光热性,使其能在3 min近红外光照射时有效杀灭表面99.9%以上的耐药型革兰氏阳性菌和阴性菌。因此,本研究成功制备了两类基于ZIF-67纳米颗粒原位合成的改性织物,验证并报道了其高效抗菌能力,为抗菌织物的制造提供了新的方案。
To effectively eliminate drug-resistant bacteria on textiles,ZIF-67 nanoparticles were synthesized in situ on the surfaces of common polyester and cotton fabrics,resulting in modified polyester(ZIF-67@Dacron)and modified cotton(ZIF-67@Cotton).The obtained fabrics were characterized by X-ray diffraction(XRD),Fourier-transform infrared spectroscopy(FTIR),and field emission scanning electron microscopy(FE-SEM).Their photothermal performance and antibacterial efficacy were also evaluated.Results confirmed the successful growth of ZIF-67 nanoparticles on both fabric types.Under nearinfrared(NIR)light irradiation for 30 seconds,the surface temperatures of ZIF-67@Dacron and ZIF-67@Cotton increased to 95℃and 120℃,respectively.This photothermal property remained stable over five heating-cooling cycles.Owing to their excellent and stable photothermal performance,both modified fabrics achieved a bactericidal efficiency of over 99.9%against drug-resistant Gram-positive and Gram-negative bacteria after just 3 minutes of NIR irradiation.In this study,we successfully fabricated two types of functional fabrics based on in situ-synthesized ZIF-67 nanoparticles,demonstrated their highly effective antibacterial properties,and presented a promising strategy for developing antibacterial textiles.
