Experimental Measurement of Fatigue Resistance of a Photochromic Diarylethene
|
Abstract:
A simple and intuitionistic method was presented to measure the fatigue resistance of photochromic diarylethene/PMMA film.The optimal exposure was analyzed by measuring the transmission of diarylethene in the bleached and colored process,in basis of which fatigue resistance was measured.The results indicate that the best exposure of bleached and colored process are 1 900 J/cm2 and 600 mJ/cm2 respectively,which shows diarylethene is insensitive to red light and sensitive to purple light.The fatigue of the ma...
