Abstract

The uniform nano-sized copper layer has been electroless plated on Al2O3 nanoparticles by feeding the solution containing copper-complex or formaldehyde or NaOH to suspending solution containing Al2O3 particles. The principal influencing factors on the uniformity of copper layer has been investigated by field-emission scanning electron microscope and laser diffraction particle size analysis. Feeding the copper-complex solution in suspending solution containing formaldehyde, NaOH and Al2O3 particles were found to be appropriate to achieve copper completely coated Al2O3 powders. The proper NaOH content in suspending solution prevents the Al2O3 nanoparticles from aggregation. The uniformly copper coated nano-sized Al2O3 composite powder can be produced at the optimazed NaOH content.
