Abstract Scope |
Nanoporous metal foams possess an interesting combination of properties including good electrical and thermal conductivity, surface-to-volume ratio and yield strength. 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 for novel combinations of chemical and mechanical properties, although further study is needed to establish the stability and properties of the microstructure at the interface. A variety of techniques such as SEM, TEM and nanoindentation will be used to characterize the foam morphology, microstructure, and mechanical behavior of these materials. |
