| Abstract: | Micron-sized composite particles consisting of spherical polymer cores and metallic copper shells were prepared. Basic cupric carbonate was coated on sulfonated polymer particles by pH-controlled hydrolysis of cupric nitrate. The thickness of the coating layer was controlled by the number of polymer particles. Addition of CO2 during aging increased the shell thickness. Electrically conducting particles were obtained by reduction with hydrogen of the composite particles obtained.
