Evaluation of response to solvents of photopolymerized cholesteric liquid crystal film

Abstract

Liquid crystal (LC) particles are fabricated from reactive mesogens possess anisotropies originating from the uniaxial alignment of rod-like molecules. We previously focused on the particles’ function from anisotropies. However, the method of “mass production of LC particles”, which is important for the application of the particles, has not been studied much. In this work, we propose mass production method like photolithography which includes selective dissolution by solvent. Therefore, we evaluated the response of ChLC film to some solvents, measuring change of reflection spectrum of film by dropped solvent.
