The primary issue in the high speed actuation application is the material design that works.  Shape memory polymers (SMPs) could provide the necessary matrix.  But to make it work in seconds requires proper design.

Prof. Mather’s team at Syracuse University, New York used non-woven carbon fibers (CNFs) into an epoxy based shape memory polymer matrix.  The idea is to fabricate a highly interconnected network which is supposed to facilitate a continuous flow electron between the CNFs.  By doing so, transfer of heat is enhanced resulting in a faster actuation speed. Nano-scale carbon fibers provided the large interfacial area for efficient heat transfer.

This work opens up application possibilities for polymer nanocomposites ranging from medical to automobile to aerospace.
