▎ 摘　　要

NOVELTY - Preparing hyperbranched polymer-modified graphene oxide in aqueous phase involves sonicating graphene oxide powder to be uniformly disperse in aqueous phase to prepare stable graphene oxide dispersion, adding diamine monomer to graphene oxide dispersion, stirring at constant temperature of 10-60 degrees C for 1-120 hours, and modifying graphene oxide with amino group-containing monomer. The diene monomer is added to prepared mixed system under stirring at constant temperature of 10-60 degrees C for 6-240 hours. The obtained solution is dialyzed, precipitated and dried to obtain final product. USE - Method for preparing hyperbranched polymer-modified graphene oxide in an aqueous phase used in fields of separation membranes, drug loading materials, and preparation of adsorption materials. ADVANTAGE - The method enables to prepare hyperbranched polymer-modified graphene oxide in aqueous phase is easy to control, has simple method, and mild condition. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing hyperbranched polymer-modified graphene oxide in aqueous phase, which involves using a dialysis bag with molecular weight of 8-30 kDa and performing dialysis in deionized water.
