چکیده انگلیسی
A kind of particle with “tremella-like” surface and core-shell structure was synthesized by pyrolysizing polycarbosilane (PCS). The “tremella-like” surface was mainly composed of graphene, which perpendicularly grew on the nucleus. The nucleus was composed of polycrystalline SiC, in which β-SiC nano-crystal randomly dispersed in amorphous matrix. This kind of particle was believed to have a great potential in the electromagnetic wave absorbing material application, because it had a huge specific surface area, core-shell structure, electromagnetic wave absorbing SiC core. The formation mechanism of this kind of particle was also discussed. It was thought that this kind of particle was derived from the small PCS molecules released during the pyrolysis of PCS precursor. Moreover, the carbon atoms participating in the growth of graphene was believed to separate out from the SiC nucleus at higher temperature.
