Abstract (en)

[origin: WO9111325A1] Shaped articles such as fibers, films, tapes, rods and the like are fabricated from composites of nonconducting, flexible chain carrier polymers and conjugated polymers. The shaped, composite articles are electrically conductive and also display excellent mechanical properties, i.e., with respect to tensile strength, elongation at break, and the like. They can also exhibit anisotropy as shown by their electrical and optical properties. They can be rendered conductive by doping. Methods of preparing the novel composite articles are disclosed as well.
