This study examined the relaxation behavior of the semi-crystalline polymer polyvinylidene fluoride (PVDF) using the thermally stimulated depolarization (TSD) method. Experimental measurements were performed on thin PVDF films irradiated with heavy ions Ne&sup(4+), Xe&sup(26+), and Bi&sup(52+) with energies of about 1.2 MeV/nucleon for Ne&sup(4+) and Xe&sup(26+), and about 3.1 MeV/nucleon for Bi&sup(52+). Analysis of the obtained TSD spectra revealed the presence of three main relaxation processes at temperatures of around –45 °C, 20 °C and 40 °C. The subsequent chemical etching of the films was found to lead to the emergence of a new relaxation process at a temperature of about –10 °C, which may be due to the appearance of a new type of relaxers on the surface of the tracks.
