Anisotropic Photomechanical Motion of Semicircular-shaped Microfibers That Contain Dyes
We prepared polyacrylamide-based fibers containing the dyes Methylene Blue or Acid Red 52 and observed their photomechanical motion upon light illumination. The fibers bend upon the application of photoillumination. The fibers recover their original shapes when photoillumination ends. The fibers bend anisotropically in a specific direction. The absorption properties and photobending behavior of the fibers are related.
