Studies on dielectric properties of polymer blend of PANI with PVDF/KDP composites

The polymer blend composites of PANI with PVDF/KDP have been synthesized by polymerization method. The different polymer blend of PANI with PVDF/KDP composites are obtained by adding 10, 20, 30, 40 and 50 wt% of KDP were added with PVDF of 1N concentration during PANI synthesis to get the polymer blend of PANI with PVDF/KDP composites. The synthesized samples of PANI and polymer blend of PANI with PVDF/KDP composites polymer were characterized by using X-Ray diffraction (XRD). The dielectric properties such as dielectric constant, dielectric loss and AC conductivity for the composites of polymer blend of PANI with PVDF/KDP composites at different weight percentages are studied as a function of frequency in the range 5 Hz–35 MHz at room temperature. It is found that the dielectric permittivity decreased exponentially at lower frequency region up to 180 Hz and then the dielectric permittivity remains constant at higher frequency region as the frequency increased. It is also observed that the dielectric permittivity decreased as the weight percentages of KDP increases in PVDF with PANI. AC conductivity increased for PANI, polymer blend of PANI with PVDF/KDP composites at 10, 20, 30 and but for 40 and 50 wt% it is decreased.
