摘要/Abstract

摘要： 用溶胶凝胶法制备了一系列掺杂钼量不同的TiO₂纳米薄膜.用XRD,SEM和CAS(ContactAngleSystem)对TiO₂薄膜的结构和性能进行了表征.结果表明,Mo⁶⁺掺杂浓度对薄膜的热致亲水性和光致亲水性均有影响,当掺Mo⁶⁺质量分数为0.75%,热处理温度为400℃时,掺钼TiO₂薄膜在黑暗中放置72h后仍能表现超亲水性.

关键词: 二氧化钛薄膜, 钼, 热致亲水性, 光致亲水性

Abstract: A series of Mo⁶⁺ doped TiO₂ thin films were prepared by sol-gel method.The obtained films were characterized by XRD,SEM,and CAS methods.It was found that the thermal-induced superhydrophilicity and photo-induced superhydrophilicity were effected by the dopant concentration,the 0.75% Mo doped TiO₂ thin film calcined at 400℃ showed superhydrophilicity even stored in the darkness for 72 h.

Key words: titanium dioxide thin film, Mo, thermal-induced hydrophilicity, photo-induced hydrophilicity
