| 摘 要： | 使用偏光显微镜（POM）和扫描电子显微镜（SEM）等测试手段,研究了PVDF/PCL共混体系在不同配比和结晶温度下晶型结构、球晶和片晶形貌的变化规律。结果表明：PVDF在低温下形成α型球晶,在高温下形成γ型球晶;两种不同晶型的球晶尺寸均随着结晶温度的升高而增大;α型PVDF环带球晶的环带间距随着体系内PCL含量的增多而增大。此外,共混体系内γ型PVDF球晶的含量也随着PCL含量的增大而增大。

| Abstract: | The crystal structure,spherulitic and lamellar morphologies of poly（vinylidene fluoride）（PVDF）/poly（ε-caprolactone）（PCL）blend were studied by means of POM and SEM.It was found that in the PVDF/PCL blends,a low crystallization temperature is in favor of the formation ofα-form PVDF crystals.However,a high crystallization temperature induces the growth ofγ-type ones.The sizes of the two types of spherulites increase with the crystallization temperature increasing.The inter-spacing distance ofα-form PVDF spherulites increases with PCL content increasing.In addition,the amount ofγ-type PVDF spherulites also increases with the crystallization temperature and the PCL content increasing. |
