Enabling liquid crystal elastomers with tunable actuation temperature.

ABSTRACT: Liquid crystalline elastomers are regarded as a kind of desirable soft actuator material for soft robotics and other high-tech areas. The isotropization temperature (T_i) plays an important role as it determines the actuation temperature and other properties, which in turn has a great effect on their applications. In the past, the common physical methods (e.g. annealing) to tune T_i is not applicable to tune the actuation temperature. The new T_i obtained by annealing immediately goes back to the old one once it is heated to a temperature above T_i, while actuation needs a temperature higher than T_i. For a fully cross-linked LCE material, once it is synthesized, the actuation temperature is fixed. Accordingly, the actuation temperature can
