Poster summary: Liquid Crystal Elastomer (LCE), which can respond to various external stimuli with large and reversible contractions, has long been recognized as potential candidate for artificial muscles. . Unlike 2D or 3D structures, fiber can deform quickly and demonstrate many actions by design pattern. However, the recent reports of LCE fibers demonstrated exciting opportunities to create intelligent textiles as well as micro-actuators with fast response.[1-3] We make LCE Fiber continuously using 3D printer set-up, and fiber contracts repeatably well. However, the low mechanical property makes LCE fiber hard to apply to weaving. Herein, we make LCE fiber stronger using a liquid crystal solution. In our experiments, we make LC Elastomer fiber stronger using a double network strategy with almost no reduction in strain compared to pristine. We also decrease the stickiness of LCE fiber which is unfavorable to clothing system, and we make a weaving sample with long LCE fiber well.
