Structural and dielectrical behavior of polypyrrole/huntite composites

In order to characterize stable composites that will contribute industrial applications, polypyrrole (PPy)/huntite were prepared by the physical method. Polypyrrole produced at various huntite concentrations (10, 20, 30, 40 wt.%). Polypyrrole/huntite was characterized Fourier transform infrared spectroscopy (FTIR), Thermal Gravimetric Analyses (TGA), Differential (DTA), Scanning electron microscopy (SEM), and dielectrical properties investigated Impedance Analyzer room temperature. The FTIR spectra show mineral coordinate with polymers through carbonate groups. TGA results indicate main cause of mass loss can be moisture in samples unreacted pyrrole monomer. SEM images have a granular spherical geometry. Dielectric measurements showed lower frequencies dielectric constants decrease exponentially an increase frequency this behavior indicates effect interfacial polarization becomes more predominant frequency.
