摘要

Electromagnetic wave (EMW)-absorbing materials occupy a strategic core position in military and national defense security. Polymer-derived silicon-based ceramics (PDCs-Si) have become ideal EMW-absorbing materials for next-generation aerospace vehicles operating in extreme environments due to their excellent high-temperature resistance, precisely designable electromagnetic properties, superior dielectric loss capabilities, and immense potential for structural–functional integration. Based on preparation methods as the classification criterion, this paper details the latest research progress of polymer-derived silicon-based composite ceramics (PDCCs-Si) for EMW absorption, introduces the preparation processes, structures, compositions, electromagnetic characteristics, and their evolution laws and influencing factors, analyzes the EMW attenuation mechanisms and strategies, and organizes and ranks the effective absorption bandwidth (EABW)—an important EMW absorption performance parameter—to elucidate the development of the EMW absorption performance of PDCCs-Si in recent years.
