Design of intelligent mesoscale periodic array structures utilizing smart hydrogel
Abstract
Intelligent mesoscale periodic array structures have been designed by combining the self-assembly properties of monodisperse polymer colloidal spheres with thermoshrinking properties of crosslinked poly(N-isopropylacrylamide) hydrogels. The periodic array structures dispersed in aqueous medium are very sensitive to environmental stimuli such as temperature and ionic species. These systems displayed dramatic and reversible optical responses against changes in temperature due to the spatial modulation in the index of refraction of the get spheres in the lattice. Precisely selecting a temperature, the diffraction efficiencies of this system can be turned on-off. The intelligent structures can be used in optical devices to protect optical sensors from high intensity lasers, and will of use in advanced optical device applications.
