▎ 摘　　要

NOVELTY - Preparing color graphene fiber, comprises (i) mixing graphene oxide dispersion liquid and centrifuging to obtain graphene oxide spinning solution, (ii) injecting graphene oxide spinning solution into a rotating coagulation bath, allowing to stand to obtain wet graphene oxide, and naturally drying to obtain graphene oxide fiber, (iii) immersing obtained graphene oxide fiber in reducing agent solution and reducing, then cooling and taking out, dipping in mixed solution of ethanol and water, taking out the fiber and then naturally drying to obtain graphite fiber, (iv) the graphite fiber in white polymer infused and solidified aqueous polyurethane solution, curing, and repeating this step to obtain white graphene fiber, and (v) immersing the white graphene fiber in pigment-containing water-borne polyurethane solution, curing, and repeating the step to obtain final product. USE - The fiber is useful for wearable product for textile. ADVANTAGE - The fiber has low cost, excellent strength and electrical conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for color graphene fiber is prepared by above mentioned method.
