研究了在空气中经紫外光辐照前后的聚 (甲基环己基硅烷 ) (简记为 :PMCS)溶液或膜的荧光光谱 .结果表明 ,随着紫外光光照时间的增加 ,PMCS溶液和膜的荧光光谱峰位依次蓝移 ,荧光强度依次降低 .并用GPC ,XPS及IR光谱研究了在空气中经紫外光辐照前后的PMCS溶液或膜 .结果表明 ,其荧光光谱峰位蓝移及荧光强度降低 ,与聚硅烷发生了光降解和光氧化过程有关
Fluorescence spectra of poly (methylcyclohexylsilane) (abbreviated as PMCS) solution or membrane before and after irradiation with ultraviolet light in air were studied.The results showed that with the increase of ultraviolet light irradiation time, PMCS solution and membrane And the fluorescence intensities decreased in turn, and the PMCS solution or membrane in air before and after UV irradiation was studied by GPC, XPS and IR spectra.The results showed that the blue shift of fluorescence peak and fluorescence Decreased intensity, and polysilanes occurred photodegradation and photooxidation process
