▎ 摘  要

NOVELTY - Preparing graphene oxide sheet of dispersant by degrading waste dander comprises sequentially mixing the waste dander with an alkaline solution and alkaline protease in order, performing alkaline degradation and enzyme degradation reactions to obtain a waste dander degradation solution, carrying out dialysis treatment, degrading waste dander to obtain graphene oxide sheet dispersant, using for intercalation dispersion of carboxylated graphene oxide to obtain graphene oxide sheet dispersion system, and freeze-drying to obtain graphene oxide sheet powder. USE - The dispersant is useful in the fields of coatings for adsorption materials with thermal conductivity, antistatic and anticorrosive functions and strengthening and toughening of polymer and cement-based complex materials. ADVANTAGE - The method: is easy,simple, economical, and rational technique.
