摘要
电磁波吸收材料在电磁污染、军事作战领域具有十分重要的意义。近年来,聚合物先驱体转化陶瓷(PDC)由于其温和的制备条件以及优异的电磁波吸收、力学、耐温性、抗氧化性等性能受到研究者的广泛关注。为了实现PDC复杂异型结构高精度成型,先进3D打印技术逐渐在该领域得到广泛关注与应用。通过对先驱体聚合物的组成及结构进行设计和制备,能够得到具有宽频、高吸收或兼具多种功能的PDC电磁波吸收材料,这为新型高性能电磁波吸收材料带来新的发展方向。本文首先对PDC的结构特点及制备工艺进行了总结;之后,重点对PDC的材料挤出3D打印及光固化3D打印研究进展进行了系统总结。最后,本文全面综述了PDC在电磁波吸收领域的研究现状,并对未来发展方向提出展望,为今后PDC吸波材料的研究提供了参考。
Electromagnetic wave(EMW)absorbing materials have shown great significance in the fields of electromagnetic pollution and military operations.In recent years,precursor-derived ceramics(PDC)have been widely concerned due to their mild preparation conditions and excellent EMW absorption,mechanics,temperature resistance,and oxidation resistance properties.To achieve high-precision molding of PDC with controlled structures,advanced 3D printing technology has gradually attracted attention and is being applied.PDC EMW absorbing materials that presented wide bandwidth and high absorption properties or multiple functions were obtained by designing their composition and structure.This brings new development directions for novel highperformance EMW absorbing materials.Here,the structural characteristics and preparation process of PDC were reviewed.Afterwards,a systematic summary was conducted on the research progress of PDC material extrusion(ME)3D printing technology and photopolymerization(VPP)3D printing technology.Finally,the research progress of PDC EMW absorption materials was comprehensively reviewed and the perspective on future directions was also been discussed.The review is expected to provide reference for future research on PDC EMW absorbing materials.
