Development of an electrodeposition nickel polymer composite by a zwitterionic surfactant

  • Published:
Journal of Surfactants and Detergents

Abstract

A nickel-fluoropolymer composite was produced by electrodeposition. This composite offers many attractive properties that make it ideal for a wide range of industrial applications; it offers very low friction and wear properties on sliding contact surfaces. Several studies were carried out with aqueous zwitterionic surfactant solutions. Critical micelle concentrations, area occupied per molecule, surface excess concentration, free energy of micellization, adsorption, and efficiency were investigated at the solution-air interface. The relationship between the adsorption isotherm at the solution-air interface and at the solid-solution interface was studied. Moreover, the mechanism of incorporation of polytetrafluoroethylene was suggested, and the relationship between thermodynamic parameters of the surfactant and the development of a composite coating was investigated. The results are discussed according to the critical micelle concentrations of the zwitterionic surfactants.
