▎ 摘 要
NOVELTY - Preparing copper modified graphene oxide alkenyl composite material comprises e.g. (i) mixing copper salt and graphene oxide dispersion liquid, and ultrasonically dispersing to obtain a mixed solution, (ii) evaporating the mixed solution to dry to obtain powder, (iii) heat treating the powder at 50-400℃ for 5-24 hours to obtain the powder after heat treatment, (iv) reducing the powder in the hydrogen-containing atmosphere to obtain reduced powder, and (v) under the vacuum environment, discharging plasma sintering the reduced powder to obtain copper-modified graphene oxide-alkenyl compound material. USE - The method for preparing copper modified graphene oxide alkenyl composite material useful in aerospace field (claimed), e.g. carrier rocket, space shuttle and satellite. ADVANTAGE - The copper modified graphene oxide alkenyl composite material has high strength, wear resistance, low coefficient of friction and excellent performance.
