▎ 摘　　要

NOVELTY - A polydopamine-modified anti-UV polybenzoxazole fiber layer-by-layer self-assembling biomimetic structure comprises polydopamine fiber as a raw material, polydopamine as an intermediate layer, and graphene oxide modified by a silane coupling agent as an outer layer. The content of polydopamine is 2-5 wt.% of polydopamine fiber and content of graphene oxide modified by silane coupling agent is 0.5-2 wt.% of polydopamine fiber. USE - Polydopamine-modified anti-UV polybenzoxazole fiber layer-by-layer self-assembling biomimetic structure. ADVANTAGE - The method is simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of the self-assembling biomimetic structure comprising preparing graphene oxide; ultrasonic cleaning polydopamine fibers to remove oil and impurities; surface coating of polydopamine; preparing silane coupling agent modified graphene oxide; and obtaining UV-resistant polydopamine self-assembled composite layer.
