NOVELTY - Hydroxyapatite/graphene oxide nanocomposite laminated structure anticorrosive pigment is claimed. The overall diameter of hydroxyapatite/graphene oxide nanocomposite laminated structure anticorrosive pigment is 400-650 nm, and the hydroxyapatite and graphene nanomaterials are assembled and laminated together by lamination. USE - Used as hydroxyapatite/graphene oxide nanocomposite laminated structure anticorrosive pigment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of anticorrosive pigment comprising preparing certain concentration of calcium nitrate solution and sodium phosphate solution, adjusting the pH of the solution to 7.4 with ethylenediamine, placing calcium nitrate and sodium phosphate solution in two beakers, and adding graphene and surfactant into the two solutions, stirring until the surfactant is fully dissolved, adding calcium nitrate solution containing graphene and surfactant into another solution dropwise, placing the entire system in an ultrasonic disperser, reacting, taking the precipitate, washing with deionized water, and drying in an oven to obtain final product, where the specific preparation conditions are: the ratio between calcium nitrate and sodium phosphate is 5:3, the surfactant is sodium polyacrylate, polyethylene glycol, Triton x-100 (RTM: Polyethylene glycol tert-octylphenyl ether) or Tween 80 (RTM: Polyoxyethylenesorbitan monooleate), and the drying temperature of the hydroxyapatite/graphene oxide nanocomposite laminate structure anticorrosive pigment product is 80-95 degrees C.
