中文摘要	the crystallization kinetics and the development of lamellar structure during the isothermal crystallization of poly (epsilon-caprolactone) (pcl) were investigated by means of differential scanning calorimetry (dsc) and real-time synchrotron small angle x-ray scattering (sr-saxs) techniques, respectively. the avrami analysis was performed to obtain the kinetics parameters. the value of avrami index, n, is about 3, demonstrating a three-dimensional spherulitic growth on heterogeneous nuclei in the process of isothermal crystallization. the activation energy and the surface free energy of chain folding for isothermal crystallization were determined according to the arrhenius equation and hoffman-lauritzen theory, respectively. in the process of nonisothermal crystallization of pcl, the value of avrami index, n, is about 4, which demonstrates a three-dimensional spherulitic growth on homogeneous nuclei. in addition, lamellar parameters were obtained from the analysis of sr-saxs data.
