▎ 摘  要

NOVELTY - Graphene oxide (GO)/poly(vinyl alcohol) (PVA)-based polymer composite fiber comprises 100 pts. wt. PVA-based polymer and 1-6 pts. wt. graphene oxide, where the graphene oxide is positioned between the PVA-based polymer chains and bound to each other by hydrogen binding, and the PVA-based polymer chains and the graphene oxide are arranged along the axial direction. USE - Used as graphene oxide/PVA-based polymer composite fiber. ADVANTAGE - The composite fiber is bulletproof, exhibits excellent protective power due to tensile strength, modulus and density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing the composite fiber, comprising manufacturing graphene oxide/PVA-based polymer spinning solution using graphene oxide, PVA-based polymer, and containing a solvent, but containing 1-6 pts. wt. of graphene oxide based on 100 pts. wt. PVA-based polymer, extruding the GO/PVA spinning solution into a coagulation bath to form a GO/PVA composite fiber, supplying moisture into the GO/PVA composite fiber, drawing the moisture-supplied GO/PVA composite fiber, and heat setting the stretched GO/PVA composite fiber.
