▎ 摘  要

NOVELTY - Manufacture of photocatalytic fiber involves dissolving or uniformly dispersing silver salt and graphene oxide in a polymer solution to prepare a stock solution for electrospinning, performing electrospinning to produce fiber non-woven blanket containing silver ions and graphene oxide at the surface and interior portion, irradiating the blanket with ultraviolet or visible light, and reducing portion of silver ions into silver metal particles, and portion of the graphene oxide to graphene. USE - Manufacture of photocatalytic fiber for masks, protective clothing, underwear and sanitary napkins (all claimed). ADVANTAGE - The photocatalytic fiber having excellent photocatalytic efficiency and catalytic activity can be produced. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) photocatalytic fiber having diameter of 80-800 nm; and (2) application of photocatalytic fiber.
