▎ 摘　　要

NOVELTY - Graphene oxide (GO) based polymeric compatibilizer, comprises a polyethylene compound with modified GO or GO hydrogen bonds, and ionic bond ploymer comprising polystyrene, polymethyl methacrylate, polyphenylene oxide, polypropylene and polyamide. USE - The graphene oxide based polymeric compatibilizer is useful for preparing benzaldehyde (claimed). ADVANTAGE - The graphene oxide based polymeric compatibilizer effectively inhibits phase separation, improves the breaking strength and thermal stability of the polymeric blend, and can be simply prepared in a wide application range. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the graphene oxide based polymeric compatibilizer, comprising uniformly mixing a compatibilizer agent in a solvent, precipitating and drying the solvent to obtain the polymer/GO complex, and pressing and melting the complex.
