Novel polymer nanocomposite for electric field-responsive solid-state thermal switch
Project Description
A thermal switch is a functional device that changes its thermal conductance in response to changes in thermal loading, helping maintain a target device or system within desired temperature ranges which are highly useful for thermal management in electronics, vehicles, and buildings. When a target device exceeds a critical temperature, the switch turns on and dissipates heat to a cold surface and vice versa. Electric field responsive polymer composites that exhibit mechanical motion/shape change or solid-state thermal conductivity variation are especially promising for such applications due to the convenience of the electric control as a reversible method for regulating thermal transport, as well as the scalability of such materials for realizing thermal switches. This project aims to develop polymer based composite materials that demonstrate modulable thermal conductivity characteristics under the action of electric fields. With nanoscale engineering of the structure and composition, these materials will be implemented in the design of thermal management devices to obtain reversible high-contrast solid-state with a high stability and rapid response.
