▎ 摘 要
NOVELTY - A gamma -ray is used for producing graphene/nickel nanocomposite material by using improved Hummer method with natural crystalline flake graphite as raw material for oxidation reaction to prepare graphite oxide; ultrasonically dispersing graphite oxide and nickel salt at amass ratio of 1:1-4 in de-ionized water to obtain mixed solution; adding isopropyl alcohol to the mixed solution and mixing them uniformly, carrying out reaction using 20-80 Gy/minute of gamma -ray dosage for 4-8 hours; and separating the product by centrifugation, and cleaning and drying. USE - Method for using gamma -ray in producing graphene/nickel nanocomposite material (claimed).
