Abstract

The invention relates to a preparation method of a strong basic graphene composite resin material and mainly used for solving the problems of low dispersibility between an inorganic nanomaterial graphene and an organic polymeric monomer and difficult uniform polymerization into spheres in the existing strong basic graphene composite ion exchange resin preparation technology. The problems are well solved by virtue of the following technical scheme: the preparation method comprises the step of treating a solution containing a polymeric monomer, a comonomer and the graphene by use of microwave and ultrasonic wave; the composite resin material is prepared from the following components in percentage by weight: a) 75-90% of polymeric monomer, b) 5-15% of comonomer, c) 0.1-5% of graphene and d) 0.1-10% of initiator; and the preparation method can be applied to the industrial production of the strong basic graphene composite ion exchange resin materials.

Description

technical field [0001] The invention relates to a preparation method of a strongly basic graphene composite resin material. Background technique [0002] Graphene is a new type of two-dimensional nano-carbon material. Since the discovery of graphene by Geim and Novoselov in the United Kingdom in 2004, graphene has set off the development of new nano-carbon materials with its unique single atomic layer structure and excellent physical and chemical properties. Research boom. The thickness of single-layer graphene is only 0.35 nm, which is made of carbon atoms sp 2 The two-dimensional honeycomb crystal structure formed by hybridization and close packing has good mechanical, optical, electrical and thermal properties. Compared with carbon nanotubes, the main performance indicators of graphene are equivalent or even better, and it avoids the insurmountable problems of chiral control and catalyst impurities in the research and application of carbon nanotubes. Utilizing the uni...
