Abstract

Articles are disclosed, comprising a polymer foam layer having a first surface and an opposite second surface; a plurality of cells between the first surface and the opposite second surface of the polymer foam layer, wherein the thickness of the polymer foam layer between the first surface and the opposite second surface is 1.0 to 1.5 times the average height of the plurality of cells; and a plurality of electrically conductive particles aligned into a plurality of columns that essentially continuously span the foam between the first surface and the opposite second surface of the polymer foam layer. The foams are useful as gaskets for electromagnetic shielding, grounding pads, battery contact conductive spring elements, and the like.
