▎ 摘　　要

NOVELTY - Preparation of reduced graphene oxide assembled polyacrylonitrile fiber comprises subjecting polyacrylonitrile fiber surface to chemical hydrolysis treatment, polyethyleneimine processing, bonding graphene oxide self-assembly on surface of polyacrylonitrile fiber by strong adsorption force and performing reduction treatment to obtain the product. USE - Preparation of reduced graphene oxide assembled polyacrylonitrile fiber (claimed) used e.g. for smart wear and electromagnetic shielding protective clothing. ADVANTAGE - The method has reduction reagent selection diversity, good reducing effect, simple operation and low production cost, is easy for industrialization, and provides reduced graphene oxide assembled polyacrylonitrile fiber, which has good conductivity and durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for reduced graphene oxide assembled polyacrylonitrile fiber having average volume resistivity of less than or equal to 30 Omega .cm, which is reduced by 12 orders of magnitude relative to the original yarn, and average volume resistivity of less than or equal to 33 Omega .cm, after washing with deionized water at room temperature for 10-20 times and drying.
