Formation of microscopic polymer structure in LCs by patterned UV irradiation using polymerization inhibitor

Research output: Contribution to journalArticlepeer-review

Abstract

We controlled the fine-pitch polymer aggregation in liquid crystals (LCs) two-dimensionally via patterned ultraviolet (UV) irradiation, where a photomask was used to precisely control the light distribution. The combination of high-intensity UV light and a polymerization inhibitor suppressed polymerization in the masked area, and improved the uniformity of LC alignment between fine-pitch polymer structures. We were able to electrically control the diffraction patterns of polymer-dispersed LCs.
