dc.description.abstractA method for the synthesis of submicron copper coated polystyrene particles by electroless deposition has been developed. In this technique, the carboxylated and sulfated polystyrene latex particles of 0.1 μm and 0.24 μm diameter, are first activated by conditioning in a solution of tetraammine palladium (II) chloride monohydrate and then plated in an electroless bath containing cupric sulfate, EDTA-disodium salt, some stabilizers and basic formaldehyde at 72 ± 1°C. The interaction between carboxylic acid groups and Pd(NH₃)₄Cl₂.H₂O has been studied using uv spectroscopy. Copper coated carboxylated polystyrene particles with a mean diameter of 0.4 μm and a standard deviation of 9% of the mean diameter have been synthesized. The size, shape and purity of these particles have been determined by SEM, EDX, and ESCA analysis. The microcrystallinity of the particles has been determined by XRD technique.
