摘要: The dielectric and morphological properties of polythiophene (PT) filled with various mass fractions chrom(III) acetylacetonate (Cr(acac)3), synthesized via chemical oxidative polymerization, are described. Significant shifts the absorption peak C-S bond in Fourier transform infrared (FT-IR) spectra indicated that metal cations mostly interacted sulfur atoms. Thermal analyses performed by differential scanning calorimetry (DSC) cold crystallization temperature (Tcc) PT decreased increasing doping level. Microstructural differences were observed between its composites electron microscopy (SEM) images. Dielectric measurements showed conductivity significantly increased level, from ˜10−7 S/m to ˜10−4 at 10 kHz 300 K.
