Abstract Since the 1960s, a new class of Si-based advanced ceramics called polymer-derived (PDCs) has been widely reported because their unique capabilities to produce various ceramic materials (e.g., fibers, matrix composites, foams, films, and coatings) versatile applications. Particularly, due promising structural functional properties for energy conversion storage, applications PDCs in these fields have attracted much attention recent years. This review highlights progress PDC field with...
Electromagnetic wave (EMW) absorbing materials have attracted much attention in recent years due to the dramatical increase of high-frequency electronic components and devices, which generate electromagnetic (EM) pollution cause serious interference (EMI). Ceramics associated (nano)composites are widely investigated as EMW because their excellent mechanical properties, chemical/thermal stabilities, oxidation/corrosion resistance. In addition outstanding performance, lightweight, flexibility...
