Abstract: Transducing photonic energy into mechanical energy is of interest in the materials community years with the objective of producing solar driven actuators. Much research has been conducted using organic and inorganic photochromes incorporated within crystals, liquid crystals, and elastomers to develop macroscopic deformable materials. Photochromic molecules adopt a different molecular and electronic structure when exposed to light. Thus, researchers in this area stress the importance of the highly ordered environments with structure changing molecules to generate mechanical deformation. Herein, we present research to challenge the conventional wisdom by observing mechanical deformation with motionless chromophores dissolved in amorphous electrospun nanofibrous polymeric materials.

A final NanoForum of the Fall semster will be held on Dec. 2.
