Effect of Wetting Agent on Morphology of Cellulose Nano-Fiber Composited Nickel Electroless Plating Film

Abstract

In this study, fabrication of cellulose nano-fiber (CNF) composited Ni plating film was attempted by electroless method using the solution with added various wetting agents. The effects of wetting agents on morphology, composition and hardness of the obtained film were investigated. At the surface of the film obtained with anionic wetting agent, more CNF fixation was observed compared with that obtained without wetting agent, and with cationic or nonionic one. Also, hardness of the film obtained with anionic one increased in approximate 25% compared with that obtained without both CNF and wetting agent.
