Abstract

An electroconductive polymer composition comprises a curable liquid thermosetting resin matrix; conductive nano-fibers such as carbon nano-tubes, carbon nano-fibers, metallic nano-fibers or non-conductive nano-fibers with an electrically conductive coating; and a particulate non-conductive phase discontinuously dispersed throughout the thermosetting matrix. The conductive nano-particles are dispersed throughout the matrix whereby when the thermosetting resin is cured, a percolation threshold is established within the thermoset matrix. The particulate non-conductive phase is selected from thermoplastic resin powders or exfoliated particles of nano-clay intercalated with the liquid thermosetting resin.
