Preparation of Nano-films by in situ Polymerization of Hydrogen-bonded Macroclusters of N-isopropylacrylamide on Silica Surfaces

The in situ photopolymerization hydrogen-bonded molecular macroclusters of N-isopropylacrylamide (NIPAAm) formed on silica surfaces in chloroform was performed for generating polymeric nano-films. The ATR–FTIR spectra showed that the structure of NIPAAm underwent a transformation from trans- to cis-...

Description
Summary:The in situ photopolymerization hydrogen-bonded molecular macroclusters of N-isopropylacrylamide (NIPAAm) formed on silica surfaces in chloroform was performed for generating polymeric nano-films. The ATR–FTIR spectra showed that the structure of NIPAAm underwent a transformation from trans- to cis-stereoisomer during polymerization. Changes in the contact angle at temperatures below and above the lower critical solution temperature (LCST) were observed at 35° and 62°, respectively.
