ABSTRACT:
A lightweight, electroconductive foam comprising an effective amount of a conductive ionic salt, a polymer capable of complexing said conductive ionic salt and an effective amount of particulate conductive material such as carbon black or metal is disclosed. Additionally, a method of preparing a lightweight electroconductive foam having a surface resistivity less than about 10.sup.10 ohms per square by an extrusion process is disclosed. Foams of the present invention exhibit relatively high conductivities yet require only relatively low amounts of particulate conductive material.
