摘要：
Two types of photochromic colorants of either spiropyran or fulgide were dispersed in thin films of blends of polymethyl methacrylate (PMMA) and styrene-butadiene-styrene copolymer (SBS) with various ratios. The thin films were illuminated with ultraviolet light (365 nm) under various temperatures. The photochromic response was monitored with a multichannel photodetector. The results show that the color form of spiropyran is more stable in polar PMMA and caused a blue shift in the absorption spectrum of merocyanine.
