摘要： 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.

摘要： A metal-assisted chemical imprinting stamp includes a porous polymer substrate and a noble metal coating formed directly on the porous polymer substrate. Fabricating the metal-assisted chemical imprinting stamp includes providing a porous polymer substrate, and disposing a noble metal on the porous polymer substrate. Metal-assisted chemical imprinting includes positioning a silicon substrate in an etching solution, contacting a surface of the silicon substrate with a stamp comprising a noble metal layer on a surface of a porous polymer substrate, and separating the silicon substrate from the stamp to yield a pattern corresponding to the noble metal layer on the silicon substrate.
