▎ 摘　　要

NOVELTY - Usage method of modified graphene in toughening modification of polymethylpentene composite involves uniformly dispersing octadecylamine-modified graphene as inorganic filler in a polymer matrix by solution mixing and forming graphene/polymethylpentene composite film by casting resultant solution. USE - Usage method of modified graphene in toughening modification of polymethylpentene composite (claimed). ADVANTAGE - The method enables simple and non-toxic preparation of toughening-modified polymethylpentene composite having excellent toughness and desired crystal structure with improved dispersibility of graphene and increased interfacial adhesion with polymethylpentene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of toughening-modified polymethylpentene composite.
