Preparation and Characterization of Nickel-Coated Carbon Fibers by Electroplating

Abstract

Electroplating technique was applied to coat carbon fibers with nickel. Before plating, the initial fibers were pretreated to improve the wettability in bath. The electroplating parameters were optimized to obtain highquality nickel-coated carbon fibers, and the effects on plating were studied. The coated carbon fibers were characterized by SEM, XRD, and XPS. The coatings are uniform, smooth, bright, and adherent to carbon fibers not only along length but also along the diameter of the filaments, and mainly composed of pure nickel. Metal-carbon-oxygen bonds are present at the interface between nickel coatings and fibers, which provides the interfacial binding force. The results of performance tests showed that the nickel-coated fibers possess a good bonding strength not less than 78.5 kPa, and exhibit excellent oxidation resistance at high temperature. Compared with the initial fibers, the wettability with aluminum is also improved obviously.

Interface Optimization and Mechanical Properties of Cu-coated Carbon Fiber Cloth/Titanium Alloy Composite

“…The glue membrane and some other grease infectants on the surface of carbon fibers are both bad for electroplating. In order to obtain uniform coating on individual fiber, CFC must be modified to improve the interfacial bonding between fibers and coating [40] . In this paper, the surface treatment of CFC before electroplating included two steps.…”

Towards Embroidered Circuit Board From Conductive Yarns for E-Textiles

“…There are several commercial conductive yarns in the market, such as silver-plated yarns, stainless steel, metallic yarns, and carbon fiber yarns [6]- [9]. Polymer containing conductive yarns can be obtained via coating with conductive material or spinning through the conductive material [10]- [13]. Silver-plated polymeric yarns are one of the most common conductive yarns due to their flexibility and ease of processability when they are compared to metal-based yarns.…”

Conductive sizing for improving electrical conductivity of carbon fiber/polyaryl ether ketone/AgNWs composites

“…Multifunctional composites are excellent candidates to combine their high mechanical properties and sufficient electrical conductivity. Multifunctional CFRP are generally obtained by the introduction of conductive fillers such as carbon nanotubes, graphene, silver nanowires or by metal deposition on CF s . Graphene and carbon nanotubes are preferred for their mechanical reinforcement, although their introduction as filler enables moderate enhancement of conductivity level.…”

“…Nickel deposition on the surface of CF was reported to enhance the electrical conductivity of the prepared composites, but no mechanical enhancement was reported. Poor compatibility between the polymer matrix and the nickel‐coated fibers suggests a possible delamination of the composites.…”
