▎ 摘  要

NOVELTY - Preparing graphene melt-blown non-woven fabric comprises (1) ultrasonically peeling the graphite oxide to prepare a graphene oxide dispersion, adding stabilizer to the dispersion, stirring uniformly, and then adding reducing agent for chemical reduction to obtain a graphene dispersion; (2) immersing the melt-blown non-woven fabric in the graphene dispersion, and then performing suction filtration to deposit the graphene on the surface of the melt-blown non-woven fabric, and draining the liquid; and (3) drying the melt-blown non-woven fabric formed with the graphene layer after completion of step (2) to obtain the graphene melt-blown non-woven fabric. USE - The method is useful for preparing graphene melt-blown non-woven fabric. ADVANTAGE - The method has simple process, makes graphene is uniformly distributed on the surface of the non-woven fabric, prepares graphene melt-blown non-woven fabric with good filtration and air permeability, tightly adheres woven fabric, and is not easy to peel off during use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene melt-blown non-woven fabric.
