Abstract�� Electroless copper plating on acrylate rubber (ACM) microspheres of micron scale was studied. By introducing a reaction control method, the continuously and uniformly covered ACM conductive microspheres with low density and core-shell structure were achieved. The morphology and composition of Cu coatings and the electrical properties of the Cu-coated ACM microspheres were investigated. It was found that Cu can be plated on the surface of ACM microspheres by electroless plating. The reaction process of electroless copper plating can be controlled by adjusting the OH-additional amounts, thus to control the morphology of Cu coatings. The Cu-coated ACM microspheres all present resistance characters that the volume resistivity declines with pressure, but remains constant with electrifing time. And the Cu-coated ACM microspheres present the special resistance behaviors with the rising of temperature.
Keywords�� rubber microspheres   Cu coatings   electroless plating   electric resistivity
