▎ 摘　　要

NOVELTY - Composite glass fiber coated with graphene on the surface of a glass fiber, is claimed. USE - The composite glass fiber coated with graphene is useful in the field of thermally conductive materials (claimed). ADVANTAGE - The composite glass fiber coated with graphene improves the mechanical properties, thermal conductivity and electrical conductivity of the material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing composite glass fiber coated with graphene comprising (i) adding graphene oxide to the dispersion of glass fibers, and uniformly dispersing ultrasonically, (ii) concentrating the dispersion of the step (i) and drying to obtain a composite glass fiber uniformly coated with graphene oxide, and (iii) irradiating the glass fiber in the step (ii) with a laser, coating the composite of the graphene uniformly by laser reduction. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of preparing composite glass fiber coated with graphene (Drawing includes non-English language text).
