| 摘 要： | 采用溶胶-凝胶法制备了TiO2薄膜和ZnO掺杂的TiOr-ZnO复合薄膜.通过X射线衍射和原予力显微镜表征了样品的晶相、晶粒尺寸和形貌.以水(H2O)作为极性溶液参照物,苯(C6H6)作为非极性溶液参照物,研究了煅烧温度、煅烧时间、薄膜层数对薄膜光致双亲性的影响.结果表明:煅烧温度和煅烧时间的不同能够导致薄膜的晶粒粒径、晶型及薄膜表面的粗糙度发生变化.从页影响薄膜的双亲性能.当煅烧温度为550℃,煅烧时间 为2h,薄膜层数为3层时.TiO2由锐钛矿相向金红石转变,薄膜的双亲性最传.TiO2-ZnO复合薄膜的晶粒粒径约为25.2nm,薄膜表面粗糙度约1.815 nm,此时,亲水角和亲油角分别为5°和4°.ZnO掺杂的TiO2复合薄膜的双亲性明显高于纯TiO2薄膜.

| Abstract: | TiO2 films and ZnO doped TiO2-ZnO composite films were synthesized by the sol-gel process.The crystal phase,size of particles and surface morphology of the film samples were characterized by X-ray diffraction and atomic force microscopy.The effects of the annealing temperature,annealing time and thickness of films on the photo-induced amphilicity of the TiO2 and TiO2-ZnO films were investigated using H2O as polarity solution and C6H6 as non-polarity solution.The results show that the annealing tem-perature ... |
