▎ 摘　　要

NOVELTY - Silicon carbide polycrystalline shell core absorbing particles contain shell core particles. The graphene in the surface of silicon carbide polycrystalline shell core absorbing particles is in the shape of fungus. The silicon carbide in silicon carbide polycrystalline shell core absorbing particles is freely dispersed in the amorphous matrix. The silicon carbide polycrystalline shell core absorbing particles are prepared by thermal decomposition of graphene-pretreated polycarbosilane. USE - Silicon carbide polycrystalline shell core absorbing particles used in textile finishing process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of silicon carbide polycrystalline shell core absorbing particles, which involves completely immersing graphite paper electrode in concentrated sulfuric acid, ultrasonically process, obtaining pretreated graphite paper electrode, subjecting to electrohydrolysis reaction in dilute sulfuric acid solution at the voltage of 5-8 V, ultrasonically washing using water, dispersing, obtaining graphene oxide solution, adding polycarbosilane solution to graphene oxide solution, immersing, drying, obtaining graphene-pretreated polycarbosilane, placing in horizontal tube furnace, and heat-treating at 1250-1400 degrees C.
