Liquid Crystalline Elastomers as Functional Damping Materials

Abstract

This report results from a contract tasking the University of Cambridge as follows: The research program shall address two issues critical to the development of damping materials based on liquid crystalline elastomers (LCE). An increase in temperature of liquid crystal transition, required for broadening the range of high-dissipation regime, will be achieved by adding new high-Tc terphenyl nematic components as side-groups to siloxane copolymer constituting the LCE network. A reduction of glass transition will be achieved by applying the micro-emulsion principle, combining the mainstream LCE with silicone liquids. This idea, emanating from some biological examples of high damping, has not yet been tried in LCE technology. (2 figures, 6 refs.)
