▎ 摘　　要

NOVELTY - Manufacture of polymer composite material reinforced with graphene oxide/carbon nanotubes composite involves (1) preparing a dispersion solution comprising graphene oxide, and carbon nanotubes, (2) mixing the dispersion solution with a solution containing a biodegradable polymer, and (3) evaporating the solvent after pouring the mixed solution prepared in the step (2) onto the substrate. USE - Manufacture of polymer composite material reinforced with graphene oxide/carbon nanotubes composite. Uses include but are not limited to coating solution, binder, textile, paper, food, drug delivery system, and cosmetics. ADVANTAGE - The polymer composite material has improved mechanical property by stably dispersing graphene oxide and carbon nanotubes using the structural properties of graphene oxide and carbon nanotubes, and without using a separate dispersant. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the polymer composite material reinforced with graphene oxide/carbon nanotubes composite, which comprises a composite comprising the graphene oxide and the carbon nanotubes, and the biodegradable polymer.
