摘要：

Conducting composites of polythiophene (PTP) and polyfuran (PF) with acetylene black (AB) were prepared via chemical oxidative polymerization of thiophene and furan in a suspension of AB in CHCl3 at room temperature using anhydrous FeCl3 as the oxidant. Formation of PTP and PF and their subsequent incorporation in PTP-AB and PF-AB composite systems were confirmed by FTIR analysis. Scanning electron microscope analysis showed the presence of compact clusters of particles in both composites. Transmission electron micrographs of PTP-AB and PF-AB composites showed formation of globular polymer encapsulated AB particles with average diameters of the order of similar to100 nm in both systems. Thermogravimetric analysis revealed that the overall thermal stability varied in the order: AB > PTP-AB > PTP and AB > PF-AB > PF. DC conductivity values for the PTP-AB and PF-AB composites were of the order of 10(-2) and 10(-3) S cm(-1), respectively. (C) 2004 Society of Chemical Industry.
