采用低温常压溶胶-凝胶法制备了锐钛矿型纳米二氧化钛涂层。采用经典的异丙醇钛水解缩合反应，然后沸水处理180 min，得到锐钛矿形式的钛涂层。光谱和微观表征表明，沸水处理后的二氧化钛薄膜以锐钛矿形式为主，晶粒尺寸约为20 nm。在纺织工业中，二氧化钛涂层是一种很有前途的抗菌光催化剂。
Anatase nanocrystalline titania coatings were produced on cotton fabrics from alkoxide solutions using a low-temperature sol-gel process under ambient pressure. Titania coatings of the anatase form were obtained via a classical hydrolysis and condensation reaction of titanium isopropoxide that was followed by a boiling water treatment for 180 min. Spectroscopic and microscopic characterizations of the titania thin films showed that the anatase form is predominant throughout the film after the boiling water treatment and that the size of the grains is about 20 nm. The titania coating on fabrics is a promising process for use as an antibacterial photocatalyst in the textile industry.
