The confined crystallization behavior of polycaprolactone (PCL) in thin and ultrathin films was studied by AFM (atomic force microscopy). It was found that the crystalline morphology of PCL depended on the film’s thickness. When the thickness is d > 2 Rg (radius of gyration), the polymer can crystallize into spherulites; when Rg < d < 2 Rg, a dense-branch morphology and dendrites could be found; when d < Rg, an “islands” structure could be obtained. Moreover, the effects of the crystallization temperature and the substrate and the molecular weight on the crystalline morphology were discussed. It was shown that the crystallization of PCL in thin films is a diffusion-controlled process, and it can be explained by diffusion-limited aggregation.
采用原子力显微镜(AFM)研究了聚己内酯(PCL)在薄膜和超薄膜中的受限结晶行为。发现PCL的结晶形态与薄膜厚度有关。当厚度为2rg(旋转半径)时，聚合物可以结晶成球晶;当Rg < d < 2 Rg时，树突呈密集枝状;当d < Rg时，可以得到“岛状”结构。此外，还讨论了结晶温度、底物和分子量对结晶形貌的影响。结果表明，PCL在薄膜中的结晶是一个扩散控制的过程，可以用扩散限制聚集来解释。
