Abstract
Provided are methods of preparing an electrically conductive polymeric foam. The methods include the following steps: (a) contacting a polymeric foam with a surfactant solution; (b) contacting the polymeric foam with a sensitizing solution; (c) contacting the polymeric foam with an activation solution; and (d) forming at least one metallic layer on the polymeric foam with an electroless plating process. Also provided are electrically conductive polymeric foams formed by such methods. The present methods and foams have particular applicability to the manufacture of EMI (electromagnetic interference) shielding devices.
