NOVELTY - Preparing nickel modified graphene absorbing material involves dispersing 100mg graphene oxide solution in 100ml deionized water ultrasonically for 2 hours to obtain graphene oxide water solution that is dispersed with 100-500mg nickel salt ultrasonically for 1 hours. The obtained mixture is added with potassium hydroxide solution to regulate pH value to 10-12. The obtained mixture is stirred with reducing agent for 2-8 hours. The obtained mixture is stirred on water bath at 60-90 degrees C for 4 hours to obtain black solution that water-washing to neutral. The washed material is dried in vacuum. USE - Method for preparing nickel modified graphene absorbing material (claimed). ADVANTAGE - The method enables to prepare nickel modified graphene absorbing material that ensures simple preparation method, low cost and low pollution. DETAILED DESCRIPTION - Preparing nickel modified graphene absorbing material involves dispersing 100mg graphene oxide solution in 100ml deionized water ultrasonically for 2 hours to obtain graphene oxide water solution that is dispersed with 100-500mg nickel salt ultrasonically for 1 hours. The obtained mixture is added with potassium hydroxide solution to regulate pH value to 10-12. The obtained mixture is stirred with reducing agent for 2-8 hours. The obtained mixture is stirred on water bath at 60-90 degrees C for 4 hours to obtain black solution that water-washing to neutral. The washed material is dried in vacuum at 50-80 degrees C for 6-10 hours. The dried material is ground to obtain nickel modified graphene fine powder that is dispersed ultrasonically in polar organic solvent to obtain modified graphene suspension liquid. The modified graphene suspension liquid and epoxy resin are stirred ultrasonically for 0.5 hours. The obtained mixture is heated in vacuum to obtain material that is stirred with curing agent uniformly. The obtained mixture is molded and vacuum-dried. The dried material is cooled to room temperature to obtain product.
