NOVELTY - Composite functional material comprises 95-105 pts. wt. nylon salt, 2-10 pts. wt. graphene oxide, 2-6 pts. wt. brucite fiber, 3-8 pts. wt. expanded graphite, 2-6 pts. wt. silane coupling agent KH560, 1-4 pts. wt. nano-carbon solution with solid content (20-25%), 1-4 pts. wt. nano titanium dioxide, 1-3 pts. wt. lignosulfonate, 1-3 pts. wt. barium stearate, 0.5-1 pts. wt. sepiolite powder, 0.2-1 pts. wt. blocking agent, 0.1-0.6 pts. wt.6-aminocaproic acid and 40-70 pts. wt.de-ionized water. USE - Used as composite functional material. ADVANTAGE - The material is resistant to high temperature, has good flame retardance and mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing composite functional material, comprising (i) mixing nylon salt, the graphene oxide, the blocking agent and 6-aminocaproic acid, dispersing ultrasonically at 50-85 degrees C for 1-3 hours to form a premix and adding premix into the autoclave; (ii) adding nanocarbon solution, brucite fiber, expanded graphite, silane coupling agent KH560, nano-titanium dioxide, lignosulfonate, sepiolite powder, and barium stearate into deionized water, stirring ultrasonically uniformly and adding into the high pressure reactor; and (iii) replacing the air in the autoclave with nitrogen at least three times, passing nitrogen gas as the protective gas, heating to 160-260 degrees C at 2-3.5 MPa, releasing the water vapor in the autoclave, maintaining pressure at 2- 3.5 MPa for1-3 hours, passing pressure inside the reactor into atmospheric pressure and discharging, in the course of the reaction, where temperature in the kettle does not exceed 280 degrees C.
