摘要：

Structure - electrical conductivity relationship was investigated for the polyaniline (PANI) pressed pellets. PANI powder was prepared from aniline sulfate (precursor) and ammonium peroxodisulfate (oxidizing agent). Pressed pellets were prepared from this powder form of PANI using LECO handpress (applied pressure 28 MPa) at room temperature. Structure and selected properties of pressed pellets have been investigated using combination of X-ray diffraction, molecular modeling and conductivity measurements in order to find the structure - electrical conductivity relationship. X-ray diffraction revealed strong preferred directional ordering of the PANI chains in pelets and conductivity measurements confirmed the anisotropy of pellets. Simulated diffractograms based on atomistic models of pure PANI are in good agreement with experimentally obtained data.
