摘要

研究了双向拉伸聚丙烯(BOPP)电容器薄膜在纵向、横向拉伸过程中微观晶体结构演化行为。通过示差扫描量热仪(DSC)、广角X射线衍射(WAXD)和固体核磁(SS-NMR)表征了不同拉伸温度、拉伸比下BOPP薄膜内部晶体结构演化规律，结果表明：较低温度下纵向拉伸，随着纵拉比增大，晶体被破坏生成了更多片晶厚度较薄的

晶；而较高温度下纵向拉伸，会发生熔体拉伸，结构中只生成一种片晶厚度较厚的

晶。同时发现，改变拉伸比并不影响

晶体含量，

晶体含量只与纵拉温度有关，升高纵拉温度有利于

晶体含量提高。而在横向拉伸过程中，升高横向拉伸温度，同样有利于生成

晶，但厚度更薄的晶体含量增多；

晶占比不受横拉比影响，此外增大横拉比有利于提高薄膜结晶度。

Abstract

The micro crystalline evolution behavior of biaxially oriented polypropylene (BOPP) film was studied during longitudinal and transverse stretching. The crystallinity and content of

crystal form of the BOPP films were characterized by differential scanning calorimetry (DSC)

wide-angle X ray diffraction (WAXD) and solid-state nuclear magnetic resonance (SS-NMR) at different stretching temperatures and draw ratios. The results show that when stretched at a lower temperature along longitudinal direction

more crystals with thinner thickness are increased as the longitudinal tension ratio increases through recrystallization

while stretched along the longitudinal direction at higher temperature

there are more

crystals possessing well-ordered crystal structure; in the process of transverse stretching

increasing the transverse stretching temperature will promote the transformation from

crystal to

crystal. Meanwhile

the ratio of

crystals is not affected by the transverse drawing ratio

while increasing the transverse drawing ratio is beneficial to improving the crystallinity of the films.
