Abstract

The invention relates to a dyeable graphene-nylon composite material and a preparation method thereof. The graphene-nylon composite material uses dimethyl sulfoxide as a solvent, and is composed of 15-35 mass percent sulfonated graphene, 60-80 nylon and 1 to 5 are prepared by the reaction of auxiliary agents. The preparation method is as follows: (1) sulfonated graphene is added to dimethyl sulfoxide to obtain a sulfonated graphene-dimethyl sulfoxide uniform dispersion; (2) the sulfonated graphene-dimethyl sulfoxide dispersion is mixed with auxiliary agents and nylon and the solvent dimethyl sulfoxide were added to the reaction kettle, and reacted at 160 ° C for 4 h to obtain the graphene-nylon composite material; (3) methylene blue or rhodamine B was added to the obtained off-white graphene-nylon composite material to make Colored graphene-nylon composites. The invention solves the problem that the carbon material-reinforced polyamide composite material cannot be dyed, broadens the application range of the graphene-nylon material, and the prepared composite material has good mechanical properties.

Description

technical field [0001] The invention belongs to the 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 have excellent mechanical properties, electrical properties, mechanical properties, as well as good solvent resistance, wear resistance, self-lubrication and processing and molding properties. is widely used in. Especially because of its good strength, wear resistance, solvent resistance and dyeability, it is widely used in clothing, rope 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. Then the ways of reinforcement and modification mainly include fiber reinforc...
