本文介绍了一种用于制备聚合物稳定的双相液晶（PSCLC）盒的去粘技术。通过剥离亲水性防粘基片，可以很好地保留聚合物基体的模板。然后可以通过在PSCLC层的两个设计的模板之间注入第三Ch-LC样品来获得所需的PSCLC单元。通过调整两个叠层模板的间距分布，可以获得接近50%的入射光反射率，并可以精确控制PSCLC单元的反射光谱带宽。从而提供了一种在50%可见光通量范围内实现宽带反射调制的方法。
An unsticking technique was applied for the fabrication of a polymer-stabilised cholesteric liquid crystal (PSCLC) cell. The template of polymer matrix in the planarly aligned cholesteric liquid crystal (Ch-LC) was perfectly preserved by lifting off the hydrophilic antisticking substrate. The desired PSCLC cell could then be obtained by injecting a third Ch-LC sample between two designed templates of PSCLC layer. By adjusting the pitch distribution in the two stacking templates, a reflectivity of nearly 50% incident light could be yielded and the bandwidth of the reflection spectrum could be controlled accurately in the PSCLC cell. Thus, a method to modulate the wide-band reflection of 50% visible light flux range was offered.
