▎ 摘　　要

NOVELTY - A graphene hybrid material is prepared by preparing nanoparticles, biomaterial solution, and graphene oxide solution, mixing nanoparticles with biomaterial solution to form biomaterial-coated nanoparticles, mixing biomaterial-coated nanoparticles with graphene oxide solution to obtain graphene oxide/nanoparticle hybrid material, and reducing graphene oxide/nanoparticle hybrid material. USE - Manufacture of graphene hybrid material (claimed) for biological and environmental pollutant sensors, electrode materials of batteries, optoelectronic devices, and adsorbents for gases and pollutants. ADVANTAGE - The hybrid material can be easily, rapidly, and eco-friendly manufactured while minimizing use of chemicals and thermal treatment because of electrostatic self-assembly properties of a biomaterial. DESCRIPTION OF DRAWING(S) - The drawing shows an electron microscope image of a graphene/nanoparticle hybrid material.
