- Abstract
ABSTRACT The photoresponsive polyhedral oligomeric silsesquioxanes (POSS) based fluorinated azobenzene-containing polymers were prepared and characterized by NMR, FT-IR, GPC, XRD, TG and UV-Vis spectra. The thermal property of the polymers was improved by the introduction of POSS cage. The trans- cis photoisomerization of the polymers in solution was similar to that of the fluorinated azobenzene monomer and in accordance with the first-order reaction kinetics equation within the first 250 seconds UV irradiation. The cotton fabrics coated with the polymers showed excellent water repellency and possessed switchable wettability under UV irradiation. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.
