Abstract

Open-celled metal foams can be fabricated through metallizing non-conductive polymer templates for better control of pore size, porosity, and inter-pore connectivity. However, the process suffers from a diffusion limit when the pore size is reduced to micro and nano scales. In this research, an electropolishing-assisted electroless deposition (EPAELD) process is developed to fabricate open-celled microcellular metal foams. To overcome the diffusion limit, a polishing current is applied in the electroless deposition process to remove metal on the surface of a polymer template, such that the ion diffusion channels will remain open and the electroless deposition reaction continues deep inside the polymer template. In this paper, a process model of the proposed EPAELD technique is developed to understand the mechanism and to optimize the proposed process.
