High tenacity, high modulus electrically conducting Polyaniline (PAn) composite fibers are prepared from air-gap spinning of lyotropic PAn/poly(p-phenylene terephthalamide), PPD-T, sulfuric acid solutions. For example, tenacity and modulus are in the range of 16 gpd and 270 gpd, respectively for 30 w.% PAn composite fiber. PAn is finely dispersed around PPD-T domains and is oriented parallel to fiber...
