Light-Induced Nontethered Rolling of Liquid Crystal Elastomer and Carbon Nanotube Composite Ring

Jingtian Kang,

et al.

Abstract: Carbon nanotubes (CNT) can enhance the mechanical and light absorption properties of the liquid crystal elastomer (LCE). Different from other ring-shaped LCE works, we proposed a ring-shaped structure using LCE-CNT composite materials that can achieve nontethered rolling with the assistance of its own gravity controlled by light. We demonstrate that the LCE-CNT composite material can lift nearly 200 times its own weight induced by light, and a cantilever beam made from it exhibits remarkable deformations to ov… Show more
