Using graphite oxide as the basic raw material, through fully self-developed green preparation process, using different small molecules as modifiers, functionalized graphene is prepared. It not only retains most of the properties of graphene, but also gives it good processing properties, which is conducive to expanding the application of graphene downstream products.
(1) Active functional groups, such as amino, carboxyl, double bond, epoxy, hydroxyl, etc., can be controlled and prepared;
(2) It is suitable for graft modification, which can be used to modify polymer materials in situ, thereby giving the composite materials electrical conductivity, thermal conductivity, high strength, flame retardant, antibacterial and antibacterial properties;
(3) This product is a stable dispersion.
With controllable active functional groups, good dispersion, narrow size distribution, green preparation process, low cost, independent intellectual property rights.
It is used in the field of polymer composite materials such as rubber, plastic, resin, fiber, etc., and can also be used in the composite of lithium battery positive and negative electrode materials, graphene thermal film, and catalyst load. Especially suitable for in-situ polymerization modified polymer materials to improve its strength, modulus, abrasion resistance, antistatic, flame retardant and other properties, while having anti-ultraviolet, far infrared and other functions.
