▎ 摘  要

NOVELTY - Continuously preparing non-woven fabric comprises using the mixed solution of graphene oxide/sodium polyacrylate as the precursor for airflow assisted spinning, collecting graphene oxide/sodium polyacrylate gel fibers with a rollable substrate, and drying to obtain graphene oxide/sodium polyacrylate non-woven fabric separated from the substrate, infiltrating the substrate with a coagulation liquid, and where the coagulation liquid is graphene oxide poor solvents, where in the mixed solution of graphene oxide/sodium polyacrylate, the mass fraction of graphene oxide is 0.2-1%, mass of sodium polyacrylate accounts for 25-75% of the total mass of the graphene oxide and sodium polyacrylate, and the weight average molecular weight of sodium polyacrylate is 1-30 million. USE - The method is useful for continuously preparing non-woven fabric. ADVANTAGE - The method: is simple, environmentally friendly, and efficient; improves the processing performance of graphene oxide solution; and achieves rapid preparation of graphene non-woven fabrics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for continuous preparation system of non-woven fabric.
