▎ 摘　　要

NOVELTY - The method involves uniformly mixing the graphene oxide nanosheets and N,N' dimethylformamide by ultrasonic to obtain a dispersion of graphene oxide nanosheets in DMF. Ethyl silicate and ethanol are measured respectively and placed in a clean beaker for ultrasonic vibration, and then the dispersion is added. 3-glycyloxypropyltrimethoxysilane, deionized water and 3-aminopropyltriethoxysilane are added successively to make it evenly mixed to obtain a precursor solution. Ultrasonic treatment is continued to disperse the reactants uniformly, and hydrolysis and condensation reactions are carried out, and the product is aged and dried to obtain the graphene oxide nanosheet composite optical functional glass. USE - Preparation method of graphene oxide nanosheet composite optical functional glass. ADVANTAGE - The graphene oxide nano-sheet composite light functional glass has high transparency, non-linear saturated characteristics, and can change the saturated absorption intensity of the glass by adjusting the doping concentration of the oxidized graphite alkyne nanometre sheet. The raw material is cheap, the operation is simple, the production cost is low, and has wide application prospect in the Q-switched laser and other fields. DESCRIPTION OF DRAWING(S) - The drawing shows a photo of oxidized graphite alkyne nano-sheet composite light functional glass.
