Abstract
Electroless Cu-coating of fly ash cenosphere particles is demonstrated in the present investigation. The electroless Cu-coating process is modified by replacing the conventional PdCl2 activator with AgNO3 activator to reduce the overall cost of the coating process. The cenosphere particles are characterized by scanning electron microscope, energy dispersive spectroscopy, auger electron spectroscopy (AES), X-ray diffraction analysis, and focussed ion beam (FIB) microscopy during and after the coating process. Relatively uniform and continuous coating thickness of 350 nm is obtained under the given coating conditions. The possible mechanism of electroless Cu-coating of cenosphere particles utilizing AgNO3 activator is suggested. Cu-coated fly ash particles find applications in manufacturing conducting polymers for EMI-shielding applications. (C) 2002 Elsevier Science B.V. All rights reserved.
