▎ 摘　　要

NOVELTY - Preparing polypropylene hydrocarbon/reduced graphene oxide coaxially clad highly conductive fiber comprises (i) exfoliating graphene oxide (GO) in a high-pressure homogenizer first, and dispersing in water in an ultrasonic generator to obtain an aqueous graphene oxide solution; (ii) placing the washed and discarded non-woven polypropylene fabrics (W-NPFs) in a mixed solution of swelling agent and surfactant for specific time, drying, and repeating the above-mentioned steps for many times to obtain modified non-woven polypropylene fabrics (T-NPFs); (iii) soaking the T-NPFs in the GO aqueous solution, drying and repeating the soaking and drying steps for many times to obtain poly, propylene hydrocarbon/graphene oxide coaxially coated fibers (GO-NPFs); and (iv) placing the GO-NPFs in a reducing agent for treatment, cleaning and drying. USE - The method is useful for preparing polypropylene hydrocarbon/reduced graphene oxide coaxially clad highly conductive fiber. ADVANTAGE - The conductive fiber has higher conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for polypropylene hydrocarbon/reduced graphene oxide coaxially clad highly conductive fiber prepared by the above mentioned method.
