▎ 摘　　要

NOVELTY - Preparing grapheme-loaded silicon dioxide hybrid filler comprises using the aqueous dispersion of the plant polyphenol physically modified graphene and the dispersion of the silane coupling agent chemically modified silica, mixing by ultrasonically stirring or agitation, thus the silane coupling agent chemically modified silica by hydrogen bonding and other physical effects to the plant polyphenols physical modification of graphene surface to obtain the grapheme-loaded silicon dioxide hybrid filler. USE - The method is useful for preparing grapheme-loaded silicon dioxide hybrid filler (claimed). ADVANTAGE - The hybrid material has excellent conducting and heat conducting functional, simple preparation technique, low cost, little pollution, and can be uniformly dispersed in the polymer matrix, thus to improve the mechanical property of the polymer nanocomposite material, and has electrical and thermal properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for grapheme-loaded silicon dioxide hybrid filler is prepared by the above mentioned method.
