摘要：

Polyaniline nanocomposite films were chemically synthesized in the presence of alginate template by varying the concentration of TiO2 in the composites. Characterization of the composite samples by FTIR, UV-Vis spectra (UV), and X-ray diffraction (XRD) indicates the formation of polyaniline-alginate/titanium dioxide (PAT) composites. The morphology analysis by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) also supports the formation of the composites. Temperature-dependent DC conductivity of the polyaniline-alginate (PA) and PAT composites was studied in the range of 300 <= T <= 500 K. UV-Vis and FTIR spectral studies reveal that the alginate is a good template for the chemical interaction between polyaniline and TiO2, which suggests that the micelles formed by the anilinium-alginate cations containing TiO2 are responsible for the transport properties of the PAT composites.
