Abstract

The invention discloses a modified graphene / bismaleimide resin composite material and a preparation method thereof, and belongs to the technical field of the preparation of nanometer composite materials. The preparation method comprises the following steps: firstly preparing graphite oxide, then preparing modified graphene, and finally preparing a composite material according to 0.1-0.5wt% of modified graphene content in the composite material. The shock strength of the modified graphene / bismaleimide resin composite material disclosed by the invention is 19.557 to 26.171KJ / m<2>, and compared with the toughness of original bismaleimide resin, the toughness of the modified graphene / bismaleimide resin composite material is increased by 3.67% to 38.74%. The interfacial bonding property between the modified graphene and the bismaleimide resin is greatly improved, so that the toughness of the bismaleimide resin is improved, and the exertion of the property of the graphene is facilitated; compared with the toughness of the bismaleimide resin and a reduced graphene / bismaleimide resin composite material, the toughness of the modified graphene / bismaleimide resin composite material is greatly improved.

Description

technical field

[0001] The invention belongs to the technical field of preparation of nanocomposite materials, in particular to a modified graphene / shuangma resin composite material and a preparation method thereof. Background technique

[0002] Graphene is made of carbon atoms with sp 2 It is composed of monoatomic layers connected by hybridization, and its basic structural unit is the most stable benzene six-membered ring in organic materials. Its theoretical thickness is only 0.35nm, which is the thinnest two-dimensional material discovered so far. The discovered two-dimensional allotrope of carbon. This special structure contains rich and peculiar physical phenomena, which make graphene exhibit many excellent physical and chemical properties. For example, the strength of graphene is the highest among the tested materials, reaching 130GPa, which is more than 100 times that of steel; Flow rate up to 1.5×10 4 cm 2 ·V -1 ·s -1 , which is twice that of the currently kno...
