Studies on Hydrophilicity Property of N-TiO2and Al/N-TiO2 Films Prepared by Magnetron Sputtering

Abstract

TiO2具有光致亲水性能,即在紫外光照下,水滴与TiO2薄膜的接触角很快变为零。这一特性使TiO2具有自洁去污、防水雾等功能,具有广阔的应用前景,因而受到广泛关注。如何改善TiO2薄膜的亲水性能,使其具有可见光活性,并使亲水性保持较长的时间,成为近年来的研究热点。本研究的目的在于探索采用磁控溅射法制备N掺杂TiO2薄膜(N-TiO2)和Al、N双掺杂TiO2薄膜(Al/N-TiO2),改善TiO2的亲水性能。主要工作包括:(1)用TiN陶瓷靶,以O2、Ar为工作气体,采用射频反应磁控溅射法制备N-TiO2薄膜。用XRD、SEM、XPS、UV-Vis、CA(contactangle接触角)等分析...TiO2 involves a unique aspect of photo-induced hydrophilicity with a water contact angle of 0º. This phenomenon has been applied to various items, such as self-cleaning tites and anti-fogging mirror. Recent investigations have focussed on the improvement of hydrophilic property of TiO2 under visible light. The aim of this investigation is to explore N-TiO2 and Al/N-TiO2 films with excellent h...学位:工学硕士院系专业:化学化工学院材料科学与工程系_材料物理与化学学号:20043601
