Electroless Nickel Plating on Disintegrated Pulp Fibers

抄録

Making pulp fiber conductive is imperative to produce conductive paper. In this study, we experimentally investigate disintegrated pulp fibers electroless plated with nickel to make the fiber conductive. In conventional electroless nickel plating on plastic materials, adding the drying process after the surface activation and catalyst adsorption processes have made electroless plating on the fiber surface possible. Our observations of the cross section of plated pulp fibers and the analysis of its elements verify that a nickel film covering the fiber surface was formed.The plate film became thicker as the plating time and temperature increased. The DC electrical resistance of the plated pulp fiber decreased to 10¹ Ω‚ as the plating time and temperature increased. The AC impedance was converged between 10¹ Ω and 10² Ω as the measurement frequency increased, which verifies that conductivity can be maintained.
