NOVELTY - 5-10 pts. wt. Acrylic acid is added to 20-50 pts. wt. graphene oxide dispersion and rapidly-stirred. 16-20 pts. wt. N,N-methylenebisacrylamide is added to solution and rapidly-stirred, and nitrogen is supplied for 20-40 minutes and gas-substituted. After completion of gas replacement, the mixture is heated and 0.05-0.2 pts. wt. ammonium persulfate is quickly added to reaction system and heated. The reaction mixture is cooled to room temperature, washed with distilled water to neutral, dried, ground and sieved to 400-500 mesh, to obtain polyacrylic acid-graphene oxide composite. USE - Preparation of polyacrylic acid-graphene oxide composite (claimed). ADVANTAGE - The method enables preparation of polyacrylic acid-graphene oxide composite having excellent compatibility, water-absorbing property and salt resistance. DETAILED DESCRIPTION - 5-10 pts. wt. Acrylic acid is added to 20-50 pts. wt. graphene oxide dispersion and rapidly-stirred. 16-20 pts. wt. N,N-methylenebisacrylamide is added to solution at room temperature and rapidly-stirred, and nitrogen is supplied for 20-40 minutes and gas-substituted. After completion of gas replacement, the mixture is heated at 50-55 degrees C and 0.05-0.2 pts. wt. ammonium persulfate is quickly added to reaction system and heated at 70 degrees C for 3-5 hours. The reaction mixture is cooled to room temperature, washed with distilled water to neutral, dried at 60-80 degrees C for 24 hours, ground and sieved to 400-500 mesh, to obtain polyacrylic acid-graphene oxide composite.
