Structural, Electrical and Thermal Properties of Composites Based on Conducting Polymer
Abstract
<jats:p>Abstract: In this work, we report the structural, thermal and electrical properties of composites consisting of polypyrrole particles in a polymethylmethacrylate matrix. Electrical resistivity analysis of these percolating composites showed a remarkable change in the conduction mechanisms below and above the percolation threshold. Structural properties were studied using X-ray diffraction, showing increases in the crystallinity index for filler concentrations above the critical percolation. Thermogravimetric analysis was used to study thermal degradation. It shows a transition from a single peak for concentrations below the percolation threshold to a double peak for concentrations above that point. The increase in the degradation temperature with the concentration of polypyrrole indicates the increase of thermal stability.Keywords: Conducting polymer, Percolation threshold, Crystallinity, Thermal degradation, X-Ray diffraction.</jats:p>
