Abstract
An article undergoing stimulus-induced deformation, that is capable of being driven rapidly and in large displacement in air, is provided. An article undergoing stimulus-induced deformation comprising, incorporated in a polymer material having a cell, a liquid crystal serving as a deformation source in a skeleton other than the cell.
Claims15
An article capable of undergoing stimulus-induced deformation comprising,
- a polymer gel comprising:
- a skeleton;
- and
- cells dispersed within the skeleton;
- and
- a liquid crystal serving as a deformation source selected from the group consisting of 4-pentyl-4′-cyanobiphenyl, 4-hexyl-4′-cyanobiphenyl, 4-hexyl-4′-cyanophenylpyridine, 4-but-3-enyloxybenzoic acid 4-methoxyphenyl ester, and 1-(4-hydroxy-4′-biphenyl)-2-[4-(10-undecenyloxy)phenyl]butane,
- wherein a mesogenic group of the liquid crystal is bound to a polymer chain of the polymer as a side chain and generates a liquid crystal phase state of an elastomer.

An article capable of undergoing stimulus-induced deformation comprising,
- a porous material comprising:
- a skeleton formed by a polymer;
- and
- cells dispersed within the skeleton;
- at least a pair of electrodes provided on surfaces of the article, and
- a component showing liquid crystallinity serving as a deformation source selected from the group consisting of 4-pentyl-4′-cyanobiphenyl, 4-hexyl-4′-cyanobiphenyl, 4-hexyl-4′-cyanophenylpyridine, 4-but-3-enyloxybenzoic acid 4-methoxyphenyl ester, and 1-(4-hydroxy-4′-biphenyl)-2-[4-(10-undecenyloxy)phenyl]butane as a main chain and/or a side chain in the polymer chain of the polymer forming the skeleton.
