“…It can be seen that two peaks characterize each resultant spectrum. The first peak is located at T m1 ¼ 343 K, whereas the second one is positioned at T m2 ¼ 359 K. Similar behavior for annealed PVC samples has been reported elsewhere [9]. As is well known, the charging process consists of the deposition of real charges either on the surface or into the bulk material at room temperature or at elevated temperature.…”

Corona charging and thermal poling have been used to prepare stretched and unstretched poly(vinyl chloride) (PVC) electrets. Short-circuit thermally stimulated depolarization, as a function of poling parameters, has been recorded. The thermal samplingÀthermally stimulated depolarization current relaxation behavior of the stretched PVC was investigated in the frame of relaxation map analysis (RMA). The analysis revealed that stretched PVC is characterized by two compensation temperatures, indicating conformational changes of PVC molecules.

“…By using these methods, many properties of polymers can be investigated such as chemical relaxation [220], cold crystallization [221] and stabilizer effects [222], influence of space charges on molecular microstructure [223] and thermal-induced structural changes [224,225], physical aging [226] and the effects of gamma and neutron radiation [227]. Individual polymers (such as polystyrene [228], polycaprolactone [229], polyoctenylene [230], polyvinylnaphthalene [231], unsaturated polyester resins [232,233]) and copolymers [234][235][236][237] as well as composites [238,239] were investigated by the TSDC and other relaxation techniques.…”

Plasticized poly(vinyl chloride)/poly(ethyl methacrylate) PVC/PEMA-based blend polymer electrolyte films containing lithium perchlorate (LiClO 4 ) as a salt were prepared by solvent casting technique. The effects of the plasticization on structural, thermal and electrical properties of the plasticized polymer blend electrolytes were investigated. The changes in the structural and complex formation properties of the materials were studied by XRD and FTIR techniques. Dielectric relaxation studies of the polymer electrolyte have been undertaken, and the results are discussed. TG/DTA technique is used to study the thermal stability. Complex impedance analysis is used to calculate the bulk resistance of the complexes. The effect of different plasticizer on the structural and physical properties of polymer blend electrolyte is well correlated.
