Abstract

Novel liquid crystalline elastomers with properties that mimic the action of a muscle have been developed. Uniaxial contraction of free standing film of the material can be achieved by heating the film through the nematic to isotropic phase transition. Thermoelastic response shows strain changes through the nematic-isotropic phase transition of about 30-35%. Retractive force of nearly 450 kPa was measured in the isotropic phase. Static workloop studies show that the visco-elastic losses in these materials to be very small.
