▎ 摘　　要

NOVELTY - A graphene material composite glass comprises block-shaped material of graphene material and gel glass substrate with different dimensions. The graphene material is two-dimensional graphene nanosheet and graphene oxide nanosheet, one-dimensional graphene nanobelts and graphene oxide nanobelts, or zero-dimensional graphene quantum dots. The content of silica in graphene quantum dots is 24 mg\mol or less. The gel glass substrate is organic silane-modified silicate glass. USE - Graphene material composite glass is used in laser protection field. ADVANTAGE - The graphene material composite glass has favorable light transmittance, mechanical property and thermal stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene material composite glass.
