▎ 摘  要

NOVELTY - Preparation of graphene coating masterbatch comprises dispersing 2-10 pts. wt. graphene oxide in 40-50 pts. wt. solvent, mixing with 10-20 pts. wt. of 2-8 mol/L copper sulfate aqueous solution, ultrasonically dispersing to obtain copper ion surface modified graphene oxide dispersion solution, mixing with emulsion carrier resin at mass ratio of 1:0.5-0.8, ultrasonically dispersing to prepare resin-coated modified graphene oxide dispersion solution, reducing using sodium borohydride to obtain modified graphene dispersion solution coated with resin and spray-drying. USE - Method for preparing graphene coating masterbatch. ADVANTAGE - The product has good dispersibility and improved compatibility.
