| Description |
The results of a TSRSP study of the electret properties of initial PLA films and PLA-based composite films with various hydrophilic nanoscale fillers are presented. It is shown that the introduction of a filler into the composite matrix changes the relaxation mechanism and leads to an improvement in the electret state stability in the PLA-based composite samples. The maximum possible value of the electret state stability in PLA-based composite film is provided by the proper electreting mode. The nature and mechanism of relaxation, as well as the stability of the electret state, is obtained by the presence of charge-dipole centres in the polymer structure. The presence and distribution form of the charge-dipole centres in the polymer matrix of PLA composites was confirmed by FTIR-spectroscopy and the attenuated total reflectance (ATR) method.
