锐钛矿TiO2膜的仿生制备及表征
Bionic Preparation and Characterization of Anatase TiO2 Film
【摘要】 根据仿生制备原理,以涂渍PVA的有机玻璃为基底,异丙醇钛-乙二醇-水为沉积液,通过控制沉积液浓度、pH值和温度,在温度小于100°C的温度下合成了TiO2膜.对TiO2膜的晶相、形貌和亲水性表征,结果表明,TiO2膜的微晶晶相结构为锐钛矿相,膜对波长大于400nm的可见光透过率为75%-85%,自然风干的膜表面均匀致密,在紫外光照10min后可达到超亲水状态.
【Abstract】 According to bionic principle,TiO2 thin film was deposited on glass substrate coated PVA by controlling concentration and pH value of titanium source depositing solution at below 100°C when Ti(OC3H7)4 was used as titanium source.The film was characterized by XRD,UV-Vis,SEM and TEM spectroscopic technology.The result showed the film exhibited anatase structure.Natural-drying film has uniform and compact morphology.The film showed 70%～85% of transmittance for ?400 nm visible-light and photo-induced superhydrophilicity under UV illumination.
