聚苯胺基复合材料研究及其应用于电磁屏蔽/吸波材料领域的进展OA

The rapid advancement of electronic technology has led to the widespread application of electromagnetic waves,particularly in information transmission and detection.This growth has concurrently increased the demand for so-lutions against electromagnetic pollution and detection,thereby accelerating the development of electromagnetic shielding materials.Among these,conductive polymers are promising due to their light weight,low cost,and tunable electrical properties,such as controllable resistance and dielectric constant.Polyaniline(PANI)is one of the most studied conduc-tive polymers;however,its standalone electromagnetic shielding and absorption performance is often limited,struggling to achieve high loss and broad bandwidth simultaneously.Current research strategies to enhance PANI's performance in-clude:(1)controlling its synthesis to produce microstructures like fibers and spirals,and(2)compounding it with other dielectric or magnetic loss materials to create high-performance composites.This review outlines the working mecha-nisms of shielding and absorbing materials,summarizes the properties and evaluation metrics of various PANI-based composites,and discusses their recent progress in this field.The advantages and challenges of these materials are ana-lyzed,and future research directions are proposed.
