The transient current were analysed by considering the effect of variation of forming time, temperature, field and composition of blend specimens. Measurements indicated that transient charging and discharging currents exhibited thermally activated character but did not show mirror image behaviour at different temperatures and field values. The log 𝐼–log 𝑡 plots were found to follow the Curie–Von Schweidler law with the value of decay constant `𝑛’ lying in the range of 0.029–2.9456. These observed characteristics also indicated that the transient charging in PVF:PVDF fluoro polyblends occur partly due to orientation of dipoles but predominantly due to trapped space charges and hopping of charge carriers amongst localized states. The modification in transient behaviour on blending PVDF with PVF have been explained on the basis of plasticization effect which increases free volume and molecular mobility and 𝑇_g modification in the trap structure.
