Abstract:
为使PLA薄膜的结晶速度进一步加快,提高PLA薄膜的结晶度,提高薄膜的耐热性和力学强度,研究了成核剂对应力诱导PLA薄膜结晶的影响.利用XRD、DSC、FTIR等表征手段,对PLA薄膜拉伸前后的结晶状态进行了表征.研究表明,简单的引入成核剂,并不能实现成核剂和应力诱导促进PLA结晶的协同作用.相反,成核剂的引入会在很大程度上阻碍应力诱导结晶.即使成核剂在与拉伸温度相同的等温冷结晶过程中能够显著的提高PLA结晶速率,但在应力诱导结晶过程中,成核剂的引入使得拉伸后薄膜结晶度较纯PLA体系拉伸后薄膜明显更低.在相对较低的拉伸温度进行实验,成核剂同样起到阻碍应力诱导结晶进行的作用.同时,实验发现相对较低的拉伸温度,更有利于应力诱导结晶的进行,薄膜在较低温度拉伸后结晶度更高且更稳定.
