Nanoporous metal foams possess an interesting combination of properties including good electrical and thermal conductivity, surface-to-volume ratio and yield strength. The values of individual properties can be tuned through changes in the foam morphology, including ligament and pore size. Dealloying, a selective corrosion process, is a versatile synthesis method for nanoporous materials as it is compatible with a wide range of alloy compositions and electrolytic solutions, and is capable of producing a wide range of pore sizes.
Gradient nanoporous metal foams present an opportunity to improve the deformation behavior of the typically brittle nanoporous foams. Different techniques ranging from SEM and TEM to nanoindentation will be used to characterize the foam morphology, microstructure, and mechanical behavior of these materials.
