TEM AND WAXS CHARACTERIZATION OF POLYANILINE PP FIBERS/

PANIPOL(TM)/ polypropylene (PP) blends can be melt spun into conductin g fibers, with a diameter of ca. 20 mu m. They have been characterized by TEM and WAXS. We find that the fibers have a highly ordered polyan iline (PANI) structure and exhibit a phase separated morphology with c ontinuous fibrils of PANI in the PP-matrix. The PANI phase has a well developed three dimensional order with a layer structure parallel to t he PANI chains and the fiber axis. The layer distance is similar to 2. 9 nm as observed from the micrographs and from the low angle X-ray ref lection. The presence of higher order X-ray reflections and the narrow peak width indicate long range order of similar to 13 nm. The continu ous PANI phase gives rise to an electrical conductivity of up to 10(-3 ) S/cm.
