Problems solved by technology

[0005] In the preparation process of graphene oxide / polymer composite materials, graphene oxide composite materials have been difficult to be popularized and used on a large scale. The problem has been difficult to be effectively solved, and single-layer or few-layer graphene oxide is difficult to prepare in batches; on the other hand, the appearance of graphene oxide aggregates has caused gaps in the interface between fillers and rubber materials, resulting in Some mechanical properties and processing properties of rubber decline
However, this method is too complicated, and there is no carboxylation treatment for graphene oxide, and there are fewer oxygen-containing functional groups on the surface, so the interface binding ability cannot be improved very well.

technical field [0001] The invention belongs to the technical field of composite material preparation, and in particular relates to a highly filled graphene oxide / resin hybrid and its preparation method and application. Background technique [0002] Graphene oxide (graphene oxide, GO) is an important derivative of graphene oxide, also known as functionalized graphene oxide. Its structure is roughly the same as that of graphene oxide, except that there are Some functional groups are mainly oxygen-containing functional groups, such as hydroxyl, carboxyl and epoxy groups, etc., where the hydroxyl and epoxy functional groups are mainly located on the base surface of the graphite sheet, while the hydroxyl and some carboxyl groups are at the edge, making some polar organic groups Molecules and polymers can be easily combined with graphene oxide to make nanocomposites.
