▎ 摘　　要

NOVELTY - Preparation of graphene oxide modified fiber, involves mixing monomer of graphene oxide, free radical scavenger, water and fiber-forming polymer to prepare a mixture, irradiating the mixture in an inert atmosphere to obtain spinning solution and spinning the spinning solution to obtain graphene oxide modified fibers. USE - Preparation of graphene oxide modified fiber used for making conductive device such as electrothermal fabric, electromagnetic shielding fabric or circuit board in electronics industry, power industry and aerospace industry (all claimed). ADVANTAGE - The method enables preparation of graphene oxide modified fiber with high conductivity, lightweight and antistatic property, and does not need to introduce reducing agent and initiators, and reduces environmental pollution.
