液晶高分子液滴形变和回缩过程的模拟

得到了描述分散相液晶高分子液滴形变和回缩过程(松驰过程)的理论模型.该模型主要以椭球形变模型为基础,引入了代表有序微区结构的介观尺寸变量和随结构变化的界面张力两个变量.结果表明:修正的理论模型预测值与松弛过程实验结果相吻合,与剪切形变过程实验结果有一定偏差,但比原始的椭球形变模型预测的结果更接近实验值.

Simulation of Deformation and Retraction of Liquid Crystalline Polymer Droplet

A modified model was established to depict the deformation and retraction process of dispersed LC-5000 droplet in PC, which was based on the ellipsoid model by introducing mesoscopic size variation of LCP domain in flow and the structure dependent interracial tension. The predicted values of the retraction process of LC-5000 deformed droplet are almost consistent with the experiment results, while the prediction of deformation process is not completely fit the experiment results, but the prediction of deformation process by the modified model is better than that of the original model.
