Facile Synthesis of Flake Copper Powder Loaded With Silver Particles

Abstract:

A fast and facile wet chemistry method has been developed for preparing monodispersed silver coated copper composite particles. Copper powder is coated using a solution containing [Ag (NH₃)] ⁺. The effect of the copper particle size distribution, the concentrations of [Ag (NH₃)] ⁺ on composite particles conductivity were investigated. The composite particle with electric conductivity of 0.8×10^-3 Ω•cm is obtained at 0.8 mol/L of Ag⁺ and1.0 g/L of dispersing agent. Copper powder loaded with silver particles morphologies range from individual particles to small islands, to the continuous multi-layers structure with Ag⁺ concentration increases.
