Wet-chemical preparation of copper foam monoliths with tunable densities and complex macroscopic shapes

Abstract

Macroscopic monoliths of copper foams have been prepared by a template-assisted wet-chemical process. The method offers subtle control over the pore size and size distribution, density and macroscopic size and shape of the metal foam. Uniaxial compression tests revealed different deformation behavior depending on the relative density. Non-vacuum-based and low-temperature routes are attractive for the cost-effective production of metal foams.
