Ultralight Co/Ag composite foams: Synthesis, morphology and compressive property

Ultralight monolithic Co/Ag composite foams were synthesized by a novel and facile method based on the traditional electroless plating. The resultant foams had remarkably low densities down to 12.7 mg/cm(3) or 99.9% porosity. Morphology of the Co/Ag composite foams was studied and compressive properties of the foam were investigated in light of its relative density. The densification strain of the foam can reach 87% because of the ultralow density. The compressive yield strength was measured and found to be in agreement with the value predicted by the cellular solids theory. (C) 2016 Elsevier Ltd. All rights reserved.
