ABSTRACT:
A method of preparing an electroconductive foam, and the foam so prepared. An electroconductive polymer such as polyaniline is dispersed in a liquid medium that includes an aromatic solvent such as xylene and an organic dopant/dispersant such as an aromatic sulfonic acid. The electroconductive polymer together with the organic dopant/dispersant constitute between 10% and 25% of the resulting dispersion. The dispersion is introduced to the pores of an electrically insulating foam matrix such as polyurethane. Excess dispersion is expelled and the foam is dried actively, to line the pores with an electroconductive lining.
