Effect of Cationic Surfactant on Deposition Behaviour in Electroless Ni-P-PTFE Composite Plating

Abstract

SUMMARYThis paper describes the effects of the presence of cationic surfactants upon the deposition behaviour of electrolessly deposited composite films. Polytetrafluoroethylene (PTFE) particles were codeposited in electroless nickel phosphorus plated films. In this study, it was found that the zeta potential of the particle surface in the plating solutions and the content of the particles in the films both depend upon the surfactant type, with a specific correlation also observed between the PTFE content in the film and the zeta potential.
