A method of making a metal-polymer composite includes dealloying metallic powder to yield porous metal particles, monitoring a temperature of the mixture, controlling the rate of combining, a maximum temperature of the mixture, or both, and combining the porous metal particles with a polymer to yield a composite. Dealloying includes combining the metallic powder with an etchant to yield a mixture. A metal-polymer composite includes porous metal particles having an average particle size of about 0.2 μm to about 500 μm and a thermoplastic or thermoset polymer. The polymer composite comprises at least 10 vol % of the porous metal particles. A powder mixture includes porous metal particles having an average particle size of about 0.2 μm to about 500 μm and a metal powder. The powder mixture includes about 1 wt % to about 99 wt % of the porous metal particles.

A simple spray coating process can be utilized to create epoxy/HNT nanocomposites with vertically aligned nanotubes. Important mechanical properties such as modulus and hardness values can be optimized and enhanced by controlling the level of nanotube dispersion during processing and the final orientation of the nanotubes. Thus, a technologically relevant processing scheme can be used to fabricate HNT nanocomposites with a high level of control over nanotube alignment and the resulting mechanical properties.
