Abstract

The invention belongs to the field of the preparation of composite fibers, and particularly relates to a graphene composite PAN (Polyacrylonitrile) fiber and a preparation method. The graphene composite PAN fiber is prepared from the following substances in parts by weight: 30 to 50 parts of graphene, 20 to 60 parts of polyurethane, 5 to 15 parts of conductive metal powder, 5 to 15 parts of anionic surfactant and 30 to 50 parts of solvent. The graphene composite PAN fiber is simple in preparation process and further, the PAN fiber which is compact is structure and further favorable in electricconduction performance can be obtained.

Description

technical field [0001] The invention belongs to the field of composite fiber preparation, in particular to a graphene composite PAN fiber and a preparation method. Background technique [0002] The performance of polyacrylonitrile fiber is very similar to that of wool, and it has good elasticity. When it is stretched by 20%, the rebound rate can still maintain 65%. It is fluffy, curly and soft, and its warmth retention is 15% higher than that of wool. Its light resistance is excellent, and its strength will only decrease by 20% after being exposed to the open air for one year. It can be made into curtains, curtains, tarpaulins, gun coats, etc.; it can resist acids, oxidants and general organic solvents, but its alkali resistance is poor. [0003] In specific applications, due to the friction between PAN fibers and objects, static electricity is easily generated. In order to reduce the static electricity of PAN fibers, domestic and foreign efforts have been devoted to the dev...
