What is it about?

The optically transparent shape memory polyimide (TSMPI) combines shape memory effects with high thermal stabilities, good mechanical properties and optical transparency.

Why is it important?

TSMPI maintained high dimensional stability and optical transparency against thermal cycles during the operating process, similar to inorganic glass. Moreover, it possesses advantages of flexibility, lightness and processability compared with fragile glass analogues.


TSMPI is expected to find applications in flexible optoelectronic devices, as well as common shape memory applications undergoing high temperature environments, such as deployable space structures, jet propulsion systems, high temperature sensors and actuators.
