尼龙1010的拉伸结晶行为及Brill转变
Drawing-induced Crystallization Behavior and Brill Transition of Nylon 1010
摘要
Abstract
The crystal transitions and crystal orientations of Nylon 1010 drawing-induced at different drawing temperatures( Td ) and drawing ratios( λ ) were studied by Differential Scanning Calorimetry( DSC), Wide-Angle X-ray Diffraction(WAXD) and two dimensional(2D) WAXD experiments. The results show that drawing is favorable to the transition of δ'form from αform of Nylon 1010 and so-called Brill transition became more obviously with drawing ratio increasing under the same temperature. New relationship of crystal form versus temperature was first discovered in which δ' form of Nylon 1010 could be gradually transformed into α form when drawn at higher drawing temperature. This is distincted from the crystallization performance of Nylon 1010 under thermal effect without drawing. The measurements of orientation degrees, based on 2D WAXS experiments, showed that crystal orientations were solely decided by the drawing ratios. Furthermore, the d spacing of (002) reflections increased with the drawing ratios, which also showed the dependence of long axis increasment on the drawing orientation.关键词
