Nowadays, photochromic fibers and films are turned towards the development of intelligent smart materials which are applied to evaluate, signalize and react to a change in color and absorbance spectra. In this work, the photochromic activity of six commercial grades of polyurethane that contains small quantities of spiropyran [1-hexyle-3,3-diméthyle-6'-nitrospiro (indoline-2',2'-benzopyran)] has been studied. The effects of film thickness, irradiation time, and SP concentration on the photochromic response of PU/SP films have been studied and also their couplings. Furthermore, the photochromic behaviors of these films under stretching and their decoloration kinetics have been investigated. The kinetics and characterization of the photochrom...
