Topology and dynamics of liquid crystalline soft matter under external fields

我已经测量了剪切应力的正弦电场下稳定的剪切流在液滴分散相的不混溶的液晶/聚合物共混物和分析它的基础上的Maffettone-Minale模型。结果表明，响应函数不是简单的弛豫型，而是阻尼振荡型，它源于速度梯度张量的反对称部分。此外，还制备了手性近晶液晶弹性体，并研究了其在电场作用下的宏观形变。对弹性体薄膜中的二维应变张量进行了定量估算

I have measured the response of shear stress to sinusoidal electric fields under steady shear flow in the droplet dispersed phase of an immiscible liquid crystal/polymer blend and analyzed it on the basis of the Maffettone-Minale model. It was obviously shown that the response function was not a type of simple relaxation but of damped oscillation, which was originated from the antisymmetrical parts of the velocity gradient tensor. Additionally chiral smectic liquid crystal elastomers were prepared and the macroscopic deformation induced by the application of electric field was investigated. The two-dimensional strain tensors in an elastomer film were quantitatively estimated
