▎ 摘  要

NOVELTY - Amino modified graphene/graphene-type molybdenum diselenide/bismaleimide composite material comprises 0.1-10 pts. wt. amino-modified graphene/graphene-type molybdenum diselenide composite nanoparticles, 30-70 pts. wt. diphenylmethane-type bismaleimide and 30-70 pts. wt. diallyl bisphenol A. USE - Used as amino modified graphene/graphene-type molybdenum diselenide/bismaleimide composite material. ADVANTAGE - The composite material: has excellent interfacial bonding strength, mechanical property and tribology property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing amino modified graphene/graphene-type molybdenum diselenide/bismaleimide composite material comprising (i) dissolving 0.1-3 g graphene oxide and 2.5 ml KH-550 in a mixed solution consisting of 25-200 ml absolute ethanol, adding 1-20 ml distilled water, heating at 78 degrees C, reacting for 4 hours, suction filtering reaction solution, making up by using absolute ethanol and deionized water, washing for many times and drying in an oven and marking it as amino-graphene oxide, (ii) dissolving 0.6-1.8 g amino-graphene oxide and 0.3-1.2 g sodium molybdate dihydrate in 50-80 ml ionized water, ultrasonically dispersing for 15-60 minutes to obtain solution A, dissolving 0.2-0.8 g selenium powder in 10-25 ml hydrazine hydrate to obtain blood red solution B in air, adding solution B into solution A, stirring at room temperature for 1-4 hours, transferring the reaction mixture into a high temperature and high pressure reactor at 180-230 degrees C for 10-24 hours, cooling to room temperature, washing reaction product for many times with deionized water and absolute ethanol and freeze-drying to obtain amino-reduced graphene oxide/molybdenum diselenide, and (iii) adding 0.1-10 pts. wt. amino-reduced graphene oxide/molybdenum diselenide, 30-70 pts. wt. diphenylmethane-type bismaleimide and 30-70 pts. wt. diallyl bisphenol A, ultrasonically dispersing at 120-300 W for 10-80 minutes, heating, melting at 130-150 degrees C, prepolymerizing for 15-80 minutes, pouring into the preheated mold, placing it in a vacuum box at 130-150 degrees C, vacuuming to remove air bubbles, placing it into a blast drying oven, curing, naturally cooling and then discharging to obtain final product, where curing process is 150 degrees C/2 hours + 180 degrees C/2 hours + 220 degrees C/4 hours + 250 degrees C/4 hours.
