▎ 摘 要
NOVELTY - High-performance polyformaldehyde fiber comprises polyformaldehyde/polyamide composite fiber and graphene fiber grafted with polyformaldehyde/polyamine. USE - The fiber is useful for concrete (claimed). ADVANTAGE - The fiber has excellent compatibility with respect to polydopamine molecule, and enhances the characteristics compression strength of the concrete. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing high performance polyformaldehyde fiber.
