|
摘要
纳米TiO_2因具备优异的物理化学特性而可被广泛地应用于化学、光学、生物、机械和电子等领域。目前,TiO_2薄膜因具备较高的光催化活性,成为一种公认的催化材料,而其光致亲水性能被用于自清洁薄膜,已形成产业化并实现了大规模的生产。本文利用溶胶-凝胶法,以玻璃为基底,制备了均匀、致密的TiO_2纳米薄膜,并研究了其摩擦学性能;同时,利用金属掺杂以及分子自组装技术,在玻璃表面制备了TiO_2纳米复合薄膜;此外,还考察了紫外光照对TiO_2薄膜摩擦学性能的影响。研究发现:
(1)采用溶胶-凝胶法制备的TiO_2纳米薄膜致密且均匀,表面具备超亲水性能;摩擦实验测得在0.5N载荷下薄膜的耐磨寿命为150s。
(2)采用Cu离子及Ni离子掺杂后,TiO_2纳米薄膜致密、均匀度依然良好,且薄膜的表面粗糙度变小;掺杂后薄膜的摩擦学性能明显改善,且当Cu离子及Ni离子掺杂量为5%(摩尔浓度)时,薄膜的抗磨减摩性能最佳。
(3)利用分子自组装技术,在TiO_2纳米薄膜表面气相沉积了一层十七氟癸基三甲氧基硅烷(FAS)单分子膜,得到TiO_2- FAS复合双层薄膜,并发现其摩擦学性能显著提高,在0.5N载荷下耐磨寿命达到550s。
(4)采用紫外光照处理后的TiO_2纳米薄膜摩擦学性能明显恶化,通过考察薄膜的亲水性能,以及紫外光照前后表面形貌的变化,发现导致恶化的原因有:紫外光照恢复了薄膜的超亲水性能从而加大了薄膜表面的粘附磨损;紫外光照后薄膜的表面形貌被破坏。其中,后者是导致薄膜摩擦学性能恶化的主要原因。
TiO_2纳米薄膜的摩擦学性能影响了其在实际应用的正常持久发挥,本文通过常用金属掺杂、分子自组装技术,显著改善了薄膜的抗磨减摩性能,并研究了紫外光照后薄膜摩擦学性能恶化的因素,这些实验结果对TiO_2纳米薄膜的应用拓展有着十分重要的意义。
Nano-TiO_2 can be widely used in chemical, optical, biological, mechanical and electrical fields for its excellent physical and chemical properties. At present, TiO_2 thin films has recognized as catalytic material because of the higher photocatalytic activity. In the same time, TiO_2 thin films have implemented in large scale as self-cleaning glass because of the photo-induced hydrophilic properties. In this paper, the homogeneous, dense TiO_2 nano thin films were prepared on the glass substrates by sol-gel process and their tribological properties were studied. We also prepared the composite nano-TiO_2 films on glass substrate by using metal doping and molecular self-assembly technology. In addition, the effect of UV irradiation on the tribological properties of TiO_2 thin films was investigated. The main results are showed as follows:
(1) The TiO_2 nano thin films prepared by sol-gel process are dense and uniform, and have super-hydrophilic properties. The wear life of the thin films is 150s at load of 0.5N.
(2) Compared to undoped TiO_2 nano thin films, the Cu-doped and Ni-doped TiO_2 nano thin films are still dense and homogeneous, having much smaller the surface roughness. The tribological properties of the doped films have improved significantly, and when the doping content of the Cu and Ni is 5% (molar concentration), the tribological properties are the best.
(3) With using the molecular self-assembly technology, (Heptadecafluoro-1,1,2,2- tetradecyl) trimethoxysilane (FAS) monolayer was deposited on the surface of TiO_2 nano thin film. It was found that their tribological performance was significantly improved, and the wear life is as long as 550s.at the load of 0.5N.
(4) After UV irradiation treatment, the tribological properties of TiO_2 thin films deteriorated significantly. UV irradiation restored the ultra-hydrophilic properties of the thin films and thus increased the adhesion wear of the film surface. On the other hand, the surface morphology of the films was destroyed after the UV irradiation. Among them, the latter was the main reason that leading to the deterioration of the tribological properties.
In fact, the tribological properties of nano-TiO_2 thin films affect their persistence in the practical application. In this paper, the tribological properties of the TiO_2 films have been significantly improved through metal doping and self-assembly techniques. Then the factors that affect the tribological properties of the films after the UV irradiation have been studied. The results here can play great role in real application of TiO_2 thin films.
