折叠表面的非晶层结构控制着聚合物层状晶体的性质,聚合物层状晶体由具有环状构象的链组成。表面张力的大小取决于环的长度和两个注入点之间的距离,环的作用包括茎的爬行运动和横向交换运动。在本工作中,局部交换运动模型的基础上的蠕虫状链模型的发展来研究的影响,横向运动的茎释放的表面张力。两个注入点之间的最佳距离由链弯曲能和构象熵的平衡决定。数值计算结果为不同环长的临近再入模型提供了依据。一个可能的解释,包括注入点的密度提出解释的机制。
The structure of amorphous layer of folding surface controls the properties of the polymer lamellar crystal, which consists of chains with a loop conformation. The surface tension depends on the length and the distance between two injection points of the loop which involving the reptation motion and lateral exchange motion of the stems. In the present work, a local-exchange motion model based on the worm-like chain model is developed to investigate the effects of lateral motion of stems on the release the surface tension. The optimal distance between two injection points is determined by the balance of chain bending energy and conformational entropy. The numerical results provide evidences to the adjacent re-entry model for various loop lengths. A possible explanation involving density of injection points is proposed to interpret the mechanism.
