▎ 摘　　要

NOVELTY - Preparation of highly dispersed modified graphene oxide comprises taking graphene oxide and 3-aminobenzeneboronic acid, ultrasonically dispersing in first solvent at mass ratio of 1-10:1, heating at 60-120 degrees C for 4-10 hours, performing solid-liquid separation to obtain 3-aminophenylboronic acid-modified graphene oxide, taking triglycidyl isocyanurate and 3-aminophenylboronic acid-modified graphene oxide, ultrasonically dispersing in second solvent at mass ratio of 1-15:1, heating at 80-180 degrees C for 12-24 hours and carrying out solid-liquid separation. USE - Method for preparing highly dispersed modified graphene oxide used for anticorrosion coating (claimed). ADVANTAGE - The product has good stability and high dispersibility; and produces anticorrosion coating with good corrosion resistance and long service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of anticorrosion coating comprising taking raw materials, uniformly dispersing at rotation speed of 2000-5000 revolutions/minute for 2-6 hours and filtering.
