▎ 摘 要
NOVELTY - Preparing graphene-nylon nanocomposite fiber comprises (i) mixing nylon chips and graphene or modified graphene, extruding and granulating to obtain graphene-nylon masterbatch, and (ii) melt-spinning the graphene-nylon masterbatch to prepare the graphene-nylon nanocomposite fiber. USE - The method is useful for preparing graphene-nylon nanocomposite fiber (claimed). ADVANTAGE - The method is simple and economical.
