▎ 摘　　要

NOVELTY - Graphene oxide hybrid flame retardant is claimed. The flame retardant is obtained by reacting ammonium polyphosphate, polyethyleneimine, bisphenol-based polyphosphate electrolytes and graphene oxide, then taking polyethyleneimine as gas source, bisphenol-based polyphosphate electrolyte as carbon source and ammonium polyphosphate as acid source to form outer layer of negatively charged three-dimensional spherical structure and positively charged graphene oxide by electrostatic adsorption to obtain flame retardant. USE - Used as graphene oxide hybrid flame retardant. ADVANTAGE - The method improves mechanical performance of material and achieves high flame-retarding effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene oxide hybrid flame retardant comprising (i) preparing bisphenol-based polyphosphate electrolyte, (ii) preparing polyethyleneimine grafted graphene oxide, and (iii) preparing graphene oxide hybrid flame retardant.
