Abstract

Abstract The present invention relates to electrically conducting organic polymers useful for spacecraft and other uses. The invention describes a number of conductive organic polymers having an electrical conductivity greater than 10-2 ohm -1 cm-1. The structures of the organic polymers contain heteroatoms such as oxygen, nitrogen and sulfur which are found in alkylene, aralkyl and aryl groups. Optionally, organic and inorganic dopants are used to increase the conductivity of the polymer. These materials are useful for conductive coatings and shielding applications, in energy storage and conversion devices, as battery anodes or cathodes, semiconductor materials and in integrated electroptics for switching, logic and display.
