Role of in-situ formed free carbon on electromagnetic absorption properties of polymer-derived SiC ceramics

Journal of Advanced Ceramics, 2020
In order to enhance dielectric properties of polymer-derived SiC ceramics, a novel single-source-precursor was synthesized by the reaction of an allylhydrido polycarbosilane (AHPCS) and divinyl benzene (DVB) to form carbon-rich SiC. As expected, the free
