| Research Abstract |
Twist nematic elastomers having a 90 degree twist alignment with definite handedness are prepared by chiral imprint method. The twist nematic elastomers exhibit a macroscopic helical form, and the reversal of the handedness is driven by temperature change. In addition, the shape transition between helicoids and spiral ribbons is induced by changing the width/thickness ratio. Cholesteric elastomers are prepared using reactive chiral LC monomers. The cholestric elastomers reflect the left-circularly polarized light with a characteristic wavelength, and the corresponding wavelength is variable by imposed strain.
