▎ 摘　　要

NOVELTY - Surface of glass substrate is subjected to hydroxylation pretreatment to obtain a treated glass substrate. A rare earth sol solution is prepared, graphene is placed in sol solution and treated to obtain rare earth-modified graphene sol. The substrate is immersed in sol, stood, the glass substrate is removed from the sol, and dried. The glass substrate is preserved at 80-120 degrees C for 30-90 minutes, heated at 600-800 degrees C, heat-preserved for 1-5 hours and naturally cooled to room temperature. Thus, rare earth-modified graphene ceramic composite film is formed on glass substrate. USE - Manufacture of rare earth-modified graphene ceramic composite film on glass substrate (claimed). ADVANTAGE - The rare earth-modified graphene ceramic composite film is easily and economically formed on glass substrate without affecting environment. The rare earth-modified graphene ceramic composite film is formed with uniformity and excellent friction reduction characteristics and abrasion resistance. DETAILED DESCRIPTION - Surface of glass substrate is subjected to hydroxylation pretreatment to obtain a treated glass substrate. Titanate solution is dissolved in ethanol, diethanol amine is added and uniformly mixed at room temperature, ethanol aqueous solution is added, N,N'-dimethylformamide is added and hydrolyzed for 1-3 hours at 15-25 degrees C to obtain rare-earth sol solution. Graphene is placed in the obtained rare earth sol solution and treated for 4-10 hours to obtain rare earth-modified graphene sol. The treated glass substrate is immersed in the rare earth modified graphene sol, stood, the glass substrate is removed from the sol, and dried. The glass substrate is preserved at 80-120 degrees C for 30-90 minutes, heated at 600-800 degrees C, heat-preserved for 1-5 hours and naturally cooled to room temperature. Thus, rare earth-modified graphene ceramic composite film is formed on glass substrate.
