中文摘要	the dielectric relaxation spectroscopy results indicate that the relaxation peak of pcl for pure pcl and pcl/liclo4 complexes shifts to a lower frequency with increasing crystallization temperature, while the amorphous, condensed structure of pcl for pure pcl and pcl/liclo4 complexes is slightly affected by crystallization temperature. these findings were obtained from small-angle x-ray scattering (saxs) measurements. to further understand the effect of crystallization temperature on the relaxation behavior of pcl and pcl/liclo4 complexes, the isothermal crystallization process of pcl and pcl/liclo4 was probed in situ by dielectric spectra measurement. the analysis indicated that the relaxation dynamics for pure pcl and pcl/liclo4 complexes decrease continuously during the isothermal crystallization process, even at the crystallization induction period. this paper presents a detailed discussion of the crystallization mechanisms of the pcl and pcl/liclo4 complexes, and the probable explanation as to the effect of crystallization temperature on the relaxation dynamics of pcl and pcl/liclo4 .
