In this study, the conducting homopolymer of indene and polyethylene/polyindene (PE/PIn) and polystyrene/polyindene (PS/PIn) composites have been electrochemically synthesized on platinum electrode in nonaqueous acetonitrile. The physical, electrochemical, thermal, and spectral properties of the synthesized PIn and their composites were investigated. The conductivities of PIn and the composites were measured with a four-probe technique. The conductivity of PIn was determined as 7.86 x 10-4 S/cm, whereas the conductivities of the PE/PIn and PS/PIn composites were determined to 6.42 x 10-5 S/cm and 5.64 x 10-5 S/cm, respectively. From Gouy scale magnetic susceptibility measurements, it was found that PIn and the composites had bipolaron natures. Fourier transform infrared spectra were taken to analyze the structural properties of PIn and the composites. The thermal properties of PIn and the PE/PIn and PS/PIn composites were investigated with thermogravimetric analysis, and it was found that they showed adequate thermal stability. According to the initial decomposition temperature among the composites, the composite including PE had the highest decomposition temperature with 450 degrees C. The synthesized composites were different in aspect of morphology when compared to PIn.(C) 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
