| 中文摘要 | crystallization behavior, structural development and morphology evolution of a series of poly (ethylene glycol)-poly(epsilon-caprolactone) diblock copolymers (peg-b-pcl) were investigated via differential scanning calorimetry (dsc), x-ray diffraction (xrd) and atomic force microscopy (afm). in these copolymers, both blocks were crystallizable and biocompatible. the mutual effects between the peg and pcl blocks were significant, leading to the obvious block composition dependence of the crystallization behavior and morphology of the peg-b-pcl copolymers. the relative block length determined which block crystallized first. the temperature-dependent xrd measurements confirmed which block crystallized first from the copolymer during the cooling procedure. single crystals of the pcl and peg homopolymers and the peg-b-pcl copolymers were obtained and observed by afm. the block (pcl or peg) crystallized first would determine the crystal morphology. the block crystallized later acted as a solvent, which was advantageous to forming perfect single crystals of the whole block copolymers. |
