Orientational structure transitions due to a photoinduced surface anchoring modulation were achieved and investigated in the case of NLC microdroplets placed between glycerol and solid surface. The boundary conditions at NLC-glycerol varied under the light action on the dendromer dopant containing azobenzene terminal fragments. At the same time, the NLC had a strong planar anchoring with the polyimide treated substrate. Numerical simulation of the observed orientational structures in NLC microdroplets were carried out.

向列液晶液滴与聚酰亚胺涂层表面接触的光诱导取向结构

在甘油和固体表面之间放置NLC微滴的情况下，实现并研究了由于光诱导的表面锚定调制而引起的取向结构转变。NLC-甘油的边界条件在含有偶氮苯末端片段的树枝状聚合物掺杂剂的光作用下发生变化。同时，NLC在聚酰亚胺处理的基材上具有很强的平面锚固性。对NLC微滴中观察到的取向结构进行了数值模拟。
