摘要
利用简单的溶胶-凝胶法制备了介孔二氧化硅纳米棒,并偶联小分子光敏剂ICPES-AZO.通过介孔二氧化硅吸附能力,对檀香803进行载香,制备出光敏性纳米香料.随后,将纳米香料附着在壁纸上,形成芳香壁纸.最后,对芳香壁纸上檀香803的释放进行了检测.研究表明,光照条件下香料可以持续释放,黑暗条件下缓慢释放,具有显著的缓控释效果.
In this article,the mesoporous silica nanocolumns were prepared via sol-gel method.The photo-sensitive small molecules were coupled with mesoporous silica nanocolumns during the preparation of these nanoparticles.With the higher surface area and pore volume,plenty of sandela 803 was encapsulated in the photo-sensitive mesoporous silica nanocolumns to form the nano fragrance,which was then applied to wallpaper.Finally,the release profiles of wallpaper treated nano fragrance were detected by gas chromatography.The results show that the wallpaper-treated nano fragrance could release sandela 803 slowly in the dark and controllably in the light.
