Interface phenomena in multifunctional liquid-crystal ferroelectric-polymer composites

我们提出了聚合物分散液晶（pdlc）的发展和微观表征，其中电光活性材料嵌入到压电或热释电宿主聚合物中。具有非活性主体聚合物的pdlc被认为是一种可电切换的光阀。利用铁、热、压电等载体，耦合不同的材料量，产生新的效应。例如，施加机械应力会导致内部电场的变化，从而改变液晶的有效折射率，从而改变光透射率。

We propose the development and microscopic characterization of polymer-dispersed liquid crystals (PDLCs) where the electro-optically active material is embedded into a piezo- or pyroelectric host polymer. PDLCs with inactive host polymers have been known for some time as electrically switchable light-valves. With a ferro-, pyro-, and piezoelectric host, new effects arise, coupling different material quantities. For example, the application of a mechanical stress leads to a change in the internal electric field, which in turn changes the effective refractive index of the liquid crystal and hence the optical transmission.
