▎ 摘　　要

NOVELTY - Flash evaporation non-woven fabric comprises high molecular fibre overlapped with each other, where the flash non-woven fabric is uniformly doped with graphene oxide sheet. USE - Flash evaporation non-woven fabric. ADVANTAGE - The flash evaporation non-woven fabric has excellent mechanical strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preapring a flash non-woven fabric, which involves: a. adding graphene oxide flakes to the spinning solvent, subjecting to uniform dispersion to obtain mixed liquid; b. dissolving the mixed liquid and the spinning polymer at 250-500℃, and a pressure of 5-50 MPa to obtain a spinning dope; and c. flashing the spinning dope to obtain polymer fibers uniformly doped with graphene oxide flakes; and d. opening polymer fibers uniformly doped with the graphene oxide flakes, laying and collecting and hot rolling.
