▎ 摘　　要

NOVELTY - Graphene/carbon nanotube polymer-based composite material comprises ultra-high-purity multi-walled carbon nanotube, graphene, polymer matrix material and dispersing agent in ratio of 1-10%. The graphene/carbon nanotube polymer matrix composite material is prepared by adding 1-10 wt.% carbon nanotubes, 0.1-1 wt.% graphene to dispersed liquid medium, ultrasonically oscillating and dispersing mixture, followed with addition of 90-95 wt.% monomer, oligomer or monomer and oligomer of polymer matrix material. The contents are mixed to obtain graphene/carbon nanotube-containing polymer matrix mixture that is irradiated with electron beam, graphene/carbon nanotubes are activated and modified under electron beam irradiation. The polymer matrix material is cured under electron beam irradiation. The obtained mixture is cured and dried at 120-140 degrees C, so that activated carbon atoms on surface of graphene/carbon nanotubes are involved in solidification of matrix material to obtain desired product. USE - Graphene/carbon nanotube polymer matrix composite material. ADVANTAGE - The graphene/carbon nanotube polymer matrix composite material has enhanced interaction between the graphene sheets, because its preparation method utilizes the synergistic effect between the one-dimensional material and the two-dimensional material between the carbon nanotube and the graphene to utilize the large aspect ratio of the carbon nanotube. The interfacial strength between matrix and substrate is enhanced by using carbon nanotubes.
