Mechanoresponsive Color Change in Cholesteric Liquid Crystal Film

Abstract

We have demonstrated that the cholesteric liquid crystal film deposited on the rubber sheet exhibits tunable, reversible and repeatable mechanochromic-responsive property, and the color can be tuned across wide visible region from brownish-orange to deep-blue. The preparation process is very simple and can be used for mass production. The mechanochromic- responsive films have potential for various applications in new mechanical sensors because of their color-tuning capability.
