聚合物变态球晶的光散射研究

STUDY ON UNUSUAL SPHERULITES BY SMALL-ANGLE LASER SCATTERING

用光散射法考察了变态球晶的形成条件和光散射图形,用有效偶极矩模型,结合傅立叶变换原理,分析了变态球晶光散射图形的成因,探讨了变态球晶的内部结构。

When PET and PBT are annealed or quenched usual or unusual spherulites grow in them, respectively. In this paper, the conditions of the formation of unusual spherulites and their scattering patterns are investigated by a small-angle laser scattering instrument .By means of the model of effective dipolar moment and the principle of Fourier transform the causes of the formation of the patterns are analysed and the internal structure of the unusual spherulites is explored.
