<jats:title>Abstract</jats:title><jats:p><jats:bold>Summary:</jats:bold> We investigate a series of glassy polymer actuators which are found to bend rapidly and reversibly in response to changes in the solvent environment. The actuators are based on hydrogen‐bonded liquid crystal networks, and bending motion is created using director profiles engineered to take advantage of the network swelling anisotropy. Strongly polar solvents easily swell the network, forcing bending in one direction, while the less polar solvents extract water to force bending in the opposite direction.</jats:p><jats:p><jats:boxed-text content-type="graphic" position="anchor"><jats:caption><jats:p>Shape variation of twisted configuration liquid crystal polymer films in acetone and water.</jats:p></jats:caption><jats:graphic xmlns:xlink="http://www.w3.org/1999/xlink" mimetype="image/jpeg" position="anchor" specific-use="enlarged-web-image" xlink:href="graphic/mgra001.jpg"><jats:alt-text>magnified image</jats:alt-text><jats:caption><jats:p>Shape variation of twisted configuration liquid crystal polymer films in acetone and water.</jats:p></jats:caption></jats:graphic></jats:boxed-text>
