摘　　要：基于纳米TiO_(2)/氟硅烷在紫外光照射下由疏水转变为超亲水的特性,制备了纳米TiO_(2)/氟硅烷涂层,并进行水接触角测试,发现在紫外光照射下其接触角由近150°降低到接近0°,实现从超疏水转变为超亲水,具有良好的自清洁效果。为探究纳米TiO_(2)含量、紫外光照射时间及不同基材对自清洁性能的影响,进行了正交试验。结果表明:在254 nm紫外光照射下,纳米TiO_(2)/氟硅烷涂层对自清洁性能的影响程度为紫外光照射时间>基材种类>纳米TiO_(2)含量;在365 nm紫外光照射下的影响程度为基材种类>紫外光照射时间>纳米TiO_(2)含量。Based on the characteristics of nano-TiO_(2)/fluosilane changing from hydrophobic to super hydrophilic under ultraviolet light,nano-TiO_(2)/fluosilane coating was prepared and the water contact angle was tested.It was found that the contact angle decreased from nearly 150°to nearly 0°under ultraviolet light,which realized the change from super hydrophobic to super hydrophilic,and had a good self-cleaning effect.In order to explore the effects of nano-TiO_(2)content,UV irradiation time and different substrates on the selfcleaning performance,orthogonal experiment was designed and carried out.The results showed that the effects of nano-TiO_(2)coating on the self-cleaning property under 254 nm UV light were as follows:UV light time>substrate type>nano-TiO_(2)content.The influence degree under 365 nm UV light was as follows:substrate type>UV light time>nano-TiO_(2)content.
