摘要

本文首次以带侧链的弱交联向列弹性体为例,考虑了取向和力学各向异性相互作用的非线性,研究了Freedericksz的阈值力学跃迁。在垂直于液晶导向器的初始取向施加机械应力的情况下,液晶弹性体导向器的重新取向具有阈值特征。分析计算了液晶分子的重定向阈值。该方法的实验实现将使我们能够确定非线性相互作用的一个系数。

On the Threshold of Mechanical Freedericksz Transition in the Liquid Crystalline Elastomer

On the Threshold of Mechanical Freedericksz Transition in the Liquid Crystalline Elastomer

The study of the threshold mechanical transition of Freedericksz is presented for the first time, taking into account the nonlinearity of the interaction of orientational and mechanical anisotropy, using weakly crosslinked nematic elastomers with side chains as an example. The reorientation of the director of the liquid crystal elastomer has a threshold character in cases where the mechanical stress is applied perpendicular to the initial orientation of the liquid crystal director. The threshold of reorientation of the liquid crystal molecules is analytically calculated. The experimental implementation of the proposed approach will allow us to determine one of the coefficients of nonlinear interaction.
