Abstract
  A new type of photochromic hydrogel, spiropyran (SP)-Polyvinylpyrrolidone (PVP)-poly (N-isopropyl acrylamide) (PNIPAM) hydrogel with functionalized SP chemically incorporated, was synthesized. The molecular structure of synthesized products was given by nuclear magnetic resonance (NMR) spectra and infrared ...  Read More
