General Bioinspired, Innovative Method for Fabrication of Surface-Nickeled Meta-aramid Fibers

Abstract

To achieve satisfactory electrical conductivity is still a challenge, without sacrificing the superior integrated performance of meta-aramid (PMIA) fibers. Here a novel, bioinspired two-step approach was reported to fabricate surface-nickeled PMIA fibers with admirable electrical conductivity. The formation of polydopamine-functionalized silver nanoparticle assemblies (DOPA@AgNAS) deposited on the surface of the PMIA fibers simply included the magnetic stirring of 3,4-dihydroxy-l-phenylalanine (DOPA) and silver ammonia in an aqueous solution at room temperature and dipping the PMIA fibers into the aqueous solution simultaneously. After, the DOPA@AgNAS functioned as the catalyst for the subsequent progress of the electroless nickel plating. The as-prepared nickel-coated PMIA fibers (DOPA@AgNAS-Ni-PMIA) possess outstanding electrically conductive properties and exhibit exceptional mechanical stability. More importantly, because of its high flexibility, DOPA@AgNAS-Ni-PMIA can be utilized in numerous fields.

Highly Conducting Surface-Silverized Aromatic Polysulfonamide (PSA) Fibers with Excellent Performance Prepared by Nano-Electroplating

“…The surface metallization of synthetic fibers seems to be a good option and has attracted considerable attention. [1,[14][15][16][17] Aromatic polysulfonamide (PSA) fiber is a kind of high-performance fiber with independent intellectual property rights in China [18,19]. Surface-metalized PSA fiber composites have advantages such as being lightweight and possessing high strength, excellent flame retardancy, outstanding chemical resistance, and high electrical conductivity.…”

Co-bath hot-batch dyeing of cotton fibers with dopamine and CI reactive red 239

“…PMIA is impregnated in a mixed solution of dopamine and silver ammonia nano ions to produce a dihydroxyphenylalanine @ silver nanoparticle assemblies (AgNAS) coating deposited on the fiber surface, which is then chemically nickel plated to prepare nickel-plated PMIA fibers (dihydroxyphenylalanine @ AgNAS-Ni-PMIA) with excellent electrical conductivity and mechanical stability. 18 The monodisperse polydopamine-silver (Ag) core-shell nanostructure has photocatalytic degradation of neutral dyes, 19 and polydopamine has excellent adhesion, 20 hydrophilicity, 21 antibacterial, 22 reducing, 23 anti-biocontamination, 24 ultraviolet resistance and corrosion resistance, etc. Moreover, polydopamine is also a green melanin-like material that can be used as a light-absorbing material, 25,26 and can be applied in the field of structural color generation.…”
