聚乙烯醇薄膜电磁屏蔽与阻燃性能研究进展
Research Progress of Electromagnetic Interference Shielding and Flame Retardancy of Polyvinyl Alcohol Films
摘要
Abstract
Introducing conductive metals and micro/nano functional particles into polyvinyl alcohol(PVA)films can endow them with multiple functions such as electromagnetic shielding,thermal conductivity,and electrical conductivity.Among them,ultrathin PVA-based electromagnetic shielding composite films have broad application prospects in the field of microelectronic devices.However,PVA composites are readily combustible,with a limiting oxygen index of only 19.0%.Once exposed to an ignition source,the PVA main chain rapidly decomposes into small molecules,leading to severe melt dripping.As application scenarios for materials continue to evolve,electromagnetic interference shielding materials are also required to possess diverse functionalities.Thus,developing PVA films that combine both electromagnetic interference shielding and flame retardancy is of significant importance.The article reviews recent research progress on PVA electromagnetic interference shielding films and their flame-retardant performance,aiming to provide a reference for the development of multifunctional electromagnetic interference shielding composites.关键词
