Abstract

The invention relates to a dyeable graphene-nylon composite material and a preparation method thereof, the graphene-nylon composite material takes dimethyl sulfoxide as a solvent, and is prepared by reaction of 15-35% by mass of sulfonated graphene, 60-80% by mass of nylon and 1-5% by mass of an auxiliary agent. The preparation method comprises the following steps: (1) adding sulfonated graphene into dimethyl sulfoxide to obtain sulfonated graphene-dimethyl sulfoxide uniform dispersion liquid; (2) adding the sulfonated graphene-dimethyl sulfoxide dispersion liquid, an auxiliary agent, nylon and a solvent dimethyl sulfoxide into a reaction kettle, and reacting at 160 DEG C for 4 hours to obtain a graphene-nylon composite material; and (3) adding methylene blue or rhodamine B into the prepared grey white graphene-nylon composite material to prepare the colored graphene-nylon composite material. The problem that the carbon material reinforced polyamide composite material cannot be dyed is solved, the application range of the graphene-nylon material is widened, and the prepared composite material has good mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of polymer composite materials, and relates to a preparation method of a dyeable graphene-nylon composite material. Background technique [0002] Nylon fibers represented by nylon 6 and nylon 66 are widely used in clothing materials and industrial materials due to their excellent mechanical properties, electrical properties, mechanical properties, and good solvent resistance, wear resistance, self-lubrication, and processing and molding properties. are widely used in. Especially because of its good strength, wear resistance, solvent resistance and dyeability, it is widely used in clothing, ropes and net materials. [0003] However, with the advancement of science and technology and the improvement of people's living standards, the requirements for the strength of nylon fibers are getting higher and higher. Therefore, the development of new nylon fiber varieties has become an increasingly important issue. ...
