NOVELTY - 70-100 pts. wt. Acrylamide is added to 20-50 mL graphene oxide dispersion, and rapidly-stirred. 0.07-0.15 pt. wt. N,N-Methylenebisacrylamide is added, rapidly-stirred and nitrogen is supplied and gas-substituted. After completion of gas replacement, the reaction mixture is heated and 0.8-2 pts. wt. ammonium persulfate is quickly added to reaction system, heated and polymerized. 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 obtain polyacrylamide-graphene oxide composite. USE - Preparation of polyacrylamide-graphene oxide composite (claimed). ADVANTAGE - The method enables preparation of polyacrylamide-graphene oxide composite having excellent compatibility, thermal stability, water-absorption property and salt resistance. DETAILED DESCRIPTION - 70-100 pts. wt. Acrylamide is added to 20-50 mL graphene oxide dispersion, and rapidly-stirred. 0.07-0.15 pt. wt. N,N-Methylenebisacrylamide is added, rapidly-stirred at room temperature, and nitrogen is supplied and gas-substituted. After completion of gas replacement, the reaction mixture is heated at 45-50 degrees C and 0.8-2 pts. wt. ammonium persulfate is quickly added to reaction system, heated at 70-90 degrees C and polymerized for 3 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 400-600 mesh, to obtain polyacrylamide-graphene oxide composite.
