A muscle-like material with a lamellar structure has been prepared for the first time from a liquid-crystalline triblock copolymer. The material consists of a repeated series of nematic-polymer blocks and conventional rubber blocks. The motor for the contraction is the reversible macromolecular-chain shape change, from stretched to spherical, of the nematic polymer that occurs at the nematic-to-isotropic phase transition.
