Utilizing the electrospinning technique, nanofibrous mats have been formed from polycaprolactone (PCL) and polylactic acid (PLA) comprising simple fluorescent dyes. Visible light irradiation of these mats leads to rapid, macroscopic shape change. We have collected videos of these motions and analyzed the deformations. This analysis includes the determination of the angular displacement and angular velocity. We have determined the elastic modulus, storage modulus, and loss modulus for these materials. These results indicate that each of these properties change during and following irradiation. A model to describe all of these results and others will be discussed.
