Abstract

The invention relates to a strong-basicity ternary composite metal-graphene-ion exchange resin material and a preparing method thereof to mainly solve the problems that in the prior art, strong-basicity ion exchange resin is poor in heat resistance and swelling resistance and likely to be decomposed and deactivated when heated in the application process. The strong-basicity ternary composite metal-graphene-ion exchange resin material is prepared from, by weight, 75-90% of polymerized monomers, 5-15% of copolymer monomers, 0.1-10% of graphene, 0.1-1% of metal particle components and 0.1-10% of an initiator. According to the technical scheme, the problems are well solved, and the strong-basicity ternary composite metal-graphene-ion exchange resin material can be used for industrial production of strong-basicity composite ion exchange resin materials.

Description

technical field [0001] The invention relates to a strongly basic ternary composite metal-graphene-ion exchange resin material and a preparation method thereof. Background technique [0002] Graphene is a new type of nano-carbon material. Since its discovery by Geim and Novoselov in the United Kingdom in 2004, graphene has set off an upsurge of research on new nano-carbon materials due to its unique single-atom layer structure and excellent physical and chemical properties. Graphene 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. In view of the outstanding properties of graphene such as high strength, high conductivity, high strength, and flexibility, graphene provides a broad space for the development of novel and high-performance polymer-based composite materials. The use of graphene and polymer matrix to prepare composite materials can s...
