摘要：

Polymethyl methacrylate-dispersed spiropyran film (SP-PMMA) and its modified film by dioctyl phthalate(DOP) were prepared by solution casting, the effects of the microstructure on their mechanical and photochromic properties were discussed. The results show that the SP-PMMA and SP-PMMA-DOP films have good mechanical strength, the " dilution effect" of SP decreases the glass transition temperature (T-g) of PMMA. The incorporation of DOP further decreases its T-g, enhances the dispersion of SP in PMMA and increases the film toughness due to the compatibilization and plasticization. SP-PMMA and SP-PMMA-DOP films exhibit the reversible photochromic behaviors. The incorporation of DOP increases the coloring and decoloring rates at room temperature.
