Description

Polystyrene particle composite nickel coatings were prepared using polystyrene particles of three types having methyl, sulfo, and amino functional groups on the particle surface. The polystyrene particle composite nickel coatings were produced in a Watts bath containing cetyl trimethyl ammonium bromide (CTAB). The maximum co-deposition ratios of the polystyrene particles having methyl, sulfo, and amino functional groups in the nickel film were about 25, 20, and 10%, respectively, at 30 mA cm－2. The order of maximum co-deposition ratio was independent of that of zeta potential of the polystyrene particles measured in the CTAB-containing Watts bath. Results show that the CTAB adsorption form and stability on the functional group-modified polystyrene surfaces are important for improvement of the co-deposition ratio.
