We utilized the thermally stimulated depolarization current (TSDC) technique for investigating the relaxation mechanism in azodye-doped ABS (acrylonitrile-butadiene-styrene) terpolymer in a wide temperature range. In contrast to the pure ABS films, the global spectra of the doped films were found to be structured. The thermal sampling (TS) technique was used in order to decompose the overlapped relaxation spectra. We verified that the compensation law is more strongly valid in case of doped samples rather than that of pure ABS samples. Moreover, this study sheds some light on the switching property of the azobenzene derivative which plays an important role in triggering the molecular orientation of the ABS host matrix, as monitored by the IR spectroscopy. |
