NOVELTY - Nanosheet graphene powder preparation involves mixing 0.03g methyl methacrylate, 9.5g 2-(dimethylamino)ethyl methacrylate, 0.5g azo-bis-isobutyrynitrile, 0.05g dibenzoyl peroxide and 0.006 g industrial grade methyl methacrylate. The obtained mixture is purified with decompression distillation method. The obtained mixture is ultrasonically cleaned for 2 hours. The obtained mixture is kept in a three three-necked bottle. The obtained three-necked bottle is equipped with condensation pipe, stirrer and nitrogen entrance. The obtained mixture is added with 0.05g azo-bis-isobutyrynitrile. USE - Method for preparing nanosheet graphene powder (claimed). DETAILED DESCRIPTION - Nanosheet graphene powder preparation involves mixing 0.03g methyl methacrylate, 9.5g 2-(dimethylamino)ethyl methacrylate, 0.5g azo-bis-isobutyrynitrile, 0.05g dibenzoyl peroxide and 0.006 g industrial grade methyl methacrylate. The obtained mixture is purified with decompression distillation method. The obtained mixture is ultrasonically cleaned for 2 hours. The obtained mixture is kept in a three three-necked bottle. The obtained three-necked bottle is equipped with condensation pipe, stirrer and nitrogen entrance. The obtained mixture is added with 0.05g azo-bis-isobutyrynitrile. The obtained mixture is stirred. The temperature of the mixture is raised at 80 degrees C for 1 hours. The temperature of the mixture is reduced at 50 degrees C. The obtained mixture is poured in a test-tube. The obtained test tube is kept in a water bath at 50 degrees C.
