Rate Theory and Relaxation Map Analysis of Iodine-Doped Poly(Ethyl Methacrylate) composite films using Thermally Stimulated Depolarization Current-Thermal Sampling (TSDC-TS) Technique

Abstract. Iodine-doped Poly (Ethyl Methacrylate) composites have been prepared using casting method. Global TSDC of the composite samples has investigated TSDC-TS technique. It is found that, global spectra pure PEMA are characterized by two relaxations. The first relaxation which observed as a shoulder in temperature range 324-333 K attributed to motion side group and named -relaxation. Whereas, second glass at Tm= 347 dipolar relaxation, i.e., -relaxation. On doping with iodine, new peak obtained high temperatures ~ 397-409 K, space charge Complex PEMA-Iodine resolved into its elementary peaks TS These used construct map (RM) all Eyring transformation. existence compensation phenomenon for also verified coordinates each point estimated. calculate density disorder (DOD) thermal expansion coefficient samples. thermodynamic parameters samples, such as, enthalpy, entropy Gibbs free energy calculated different poling temperatures.
