▎ 摘　　要

NOVELTY - A modified first substitution rate increased polymerization temperature-sensitive method for preparing graphene oxide comprises initiating polymerization to N-isopropylacrylamide (NIPAM), grafting the polymer onto surface of oxidized graphite alkene, where terminal end is provided with azide group as atom transfer radical polymerization initiator for initiating NIPAM polymerization, and obtaining terminal azido group poly(N-isopropylacrylamide) (PNIPAM); and reacting alkynyl group molecules with oxidized graphene and providing PNIPAM azide group to obtain temperature-sensitive graphene. USE - Modified first substitution rate increased polymerization temperature-sensitive method for preparing graphene oxide (claimed). ADVANTAGE - The method solves prior art azide group low substitution rate.
