Silicon carbide/graphene nano sheet composite material and preparation method thereof |
| abstract |
The invention relates to a preparation method of a silicon carbide/graphene nano flaky composite material, which comprises the following steps: 1) preparing a graphene nanosheet and silicon monoxide powder mixed dispersion liquid, wherein the molar ratio of graphene to silicon oxide in the mixed dispersion liquid is (2-1): (1-2.5); 2) drying the mixed dispersion liquid to obtain a precursor; 3) calcining the precursor under the conditions that the vacuum degree is 0.03-0.1MPa and the temperature is 1000-1250 ℃ to obtain a crude product of the silicon carbide/graphene nanosheet; 4) and carrying out silicon removal treatment on the crude product to obtain the silicon carbide/graphene nanosheet. The preparation method of the silicon carbide/graphene nanosheet composite material is simple in process, low in cost and easy for industrial production. |
