本文应用偏光显微镜,扫描电子显微镜和小角激光光散射(SALS)法,研究了聚对苯二甲酸乙二酯的亚宏观结构形态,结果表明其本体结晶至少存在两类不同形态。一类是当轴与球晶径向成45°角。
In this paper, the sub-macrostructure of polyethylene terephthalate was studied by polarized light microscopy, scanning electron microscopy and small-angle laser light scattering (SALS) method. The results show that there are at least two different morphologies of bulk crystallites. One type is when the axis and the spherulite radial into a 45 ° angle.
