Abstract

With the development of electronic communication technology, the issues of electromagnetic (EM) wave pollution have become increasingly prominent, and the requirements for EM wave absorbing materials are rising. Polypyrrole (PPy), an important type of conductive polymers, has attracted increasing attention in the applications of EM wave absorbing due to their facile synthesis process, low density, good conductivity, corrosion resistance, and stable chemical properties. Various PPy-based composite materials exhibit excellent electromagnetic absorbing properties and have been widely reported in the literature. In this review, the recent development and understanding of PPy and PPy-based composites materials in the applications of EM wave absorption are summarized in detail. In particular, as a conductive loss-type absorbing material, we focus on the design and fabrication of PPy-based composites and explore the significant impact of EM parameters on the EM wave absorbing properties. Finally, perspectives are provided for future directions of advanced PPy and PPy-based composites for microwave absorbers.
