| Abstract : | |
| Thermally stimulated depolarization currents (TSDC) have been measured in short-circuit configuration as the function of temperature, field and composition on pure PVF and polyblends containing different wt% of poly (vinly fluoride) (PVF) and poly (vinlylidene fluoride) (PVDF). DSC thermo gram was used to characterize the Tg of pure PVF and PVF/PVDF polyblend (i.e. 50:50). To evaluate the polar C-F group in pure PVF and PVF/PVDF polyblends FTIR spectrum was used. Such measurements have clearly indicated that polarization in pure PVF and PVF: PVDF polyblends arise due to dipolar orientation and trapping of injected space charge carriers. The polarization phenomenon is modified on blending PVDF in PVF. The electrets made of PVF: PVDF polyblends store considerable amount of charge for a sufficiently long period of time. |
