-- Matexcel, a leading service provider in material science, now provides quality graphene modification services for customers worldwide to help with their research.
Graphene is a two-dimensional carbon nanomaterial with excellent electrical, thermal, mechanical and other physical and chemical properties. Its applications cover the fields of batteries, sensors, supercapacitors and composite materials. However, the strong π-π interaction and high specific surface energy between graphene sheets lead to strong chemical inertness and tend to aggregate, which limits the performance of its excellent performance. Therefore, graphene must be appropriately modified to promote its dispersion in the solvent or matrix resin, and further expand the application range of graphene.
Generally speaking, the surface modification of graphene includes chemical modification (covalent bond modification), physical modification (non-covalent bond modification) and element doping modification. Chemically modified graphene has relatively high stability, but the reaction conditions for chemical modification are relatively harsh, and generally require conditions such as strong acid, strong oxidant, high temperature, or catalyst, and the operation is complicated. At the same time, chemical modification will also affect the conjugated structure of graphene sheets, causing defects and then affecting the physical and chemical properties of graphene (such as conductivity, barrier properties and mechanical properties). Compared with chemical modification, physical modification has less damage to the conjugated sheet structure of graphene, and has less impact on the physical and chemical properties of graphene, and the reaction operation is simple and convenient, but the stability is poorer than chemical modification. The element doping modification of graphite mainly uses annealing treatment, ion bombardment, arc discharge method and other methods to dope elements such as nitrogen, phosphorus, boron, sulfur, silicon and other elements into the graphene to replace the defects on the graphene sheet, giving graphene new properties.
With years of experience in material research, especially in graphene research, Matexcel now offers all the strategies for graphene modification, including chemical modification, polymer grafting and doping. Customized services can also be tailored according to different needs.
