Bistable Color‐Tunable Liquid Crystal Fiber by the Method of Mechanical Drawing with Synchronous Ultraviolet Polymerization

A color‐tunable fiber is demonstrated to reflect colors by switching the electric field on a chiral liquid crystal (CLC) with different helical twisting powers. With the purpose of bistability and low power consumption, the mechanism of the CLC fiber proposed in this study is an electric‐field‐induced phase change. To maintain the balance of wearable flexibility and mechanical stability, the liquid crystal fiber is constructed by the method of...
