Abstract

The invention belongs to the technical field of graphene, and particularly relates to a graphene oxide master batch as well as preparation and application thereof. According to the technical scheme, agraphene oxide aqueous solution is directly added into a waterborne polyurethane emulsion with good intermiscibility, and dispersion of graphene oxide in the waterborne polyurethane emulsion is promoted. A polypeptide condensing agent is added, so that amidation and esterification reactions between active groups such as carboxyl on the surface of the graphene oxide and active groups such as hydroxyl and amino on a waterborne polyurethane chain are promoted; the interface bonding strength of the graphene oxide and the waterborne polyurethane is enhanced, the good dispersion of the graphene oxide in the waterborne polyurethane is further promoted, and a slow demulsification process is formed. The obtained graphene oxide master batch can be directly mixed with polyester, polyamide, thermoplastic polyurethane and other high-molecular resin and then subjected to melt extrusion, thermal reduction of graphene oxide is achieved, and the problems that graphene powder is difficult to feed, large in dust amount, prone to agglomeration, weak in binding power with matrix resin and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of graphene, and more specifically relates to a graphene oxide masterbatch and its preparation and application. Background technique [0002] In recent years, graphene has received extensive attention and research in the fields of energy storage materials, composite materials, and optoelectronic materials due to its excellent mechanical properties, electrical and thermal conductivity, etc. Among them, in the field of composite materials, graphene has the advantages of less addition and greatly improved material performance, which is obviously superior to traditional functional fillers. However, problems such as high surface tension and easy agglomeration of graphene also affect the full performance of graphene. [0003] The master batch method refers to the concentrated body prepared by mixing a large amount of fillers, additives, and a small amount of carrier resin in the process of plastic and rubber proc...
