NOVELTY - Preparation of graphene oxide/polyacrylic acid imitation shell mother-of-pearl layer composite material, involves dissolving 15-25 pts. wt. polyacrylic acid in 80-90 pts. wt. deionized water and stirring for 14-16 hours to obtain a polyacrylic acid solution, dispersing 10-20 pts. wt. graphene oxide in 65-75 pts. wt. deionized water, stirring and ultrasonically processing for 2-3 hours to obtain graphene oxide water dispersion, mixing two solutions, stirring uniformly, and separating by a 0.22 mu m microporous PTFE filter in a vacuum suction device and drying at 25-35 degrees C and peeling off. USE - Preparation of graphene oxide/polyacrylic acid imitation shell mother-of-pearl layer composite material. ADVANTAGE - The preparation of graphene oxide/polyacrylic acid imitation shell mother-of-pearl layer composite material is simple, rapid and easy to operate. The composite film of graphene oxide-polyacrylic acid imitation shell brick ash layered structure having excellent mechanical properties successfully prepared.
