摘要:
为开发具有高效光催化自清洁功能的环境友好材料，通过将聚二甲基硅氧烷（PDMS）和二氧化钛（TiO2，P25）在乙酸乙酯中进行光接枝反应，制备得到复合涂层，然后喷涂于织布表面得到PDMS@P25织布。采用接触角仪、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、拉曼光谱对其进行表征，探讨了PDMS、TiO2及溶剂乙酸乙酯的用量对PDMS@P25织布超疏水性能的影响，考察了PDMS@P25织布对有机染料尼罗红的紫外光降解情况。结果表明：经60 min的紫外照射后，PDMS@P25织布可将水体中尼罗红完全降解。同时PDMS@P25织布在水体中可防止其表面被泥沙和有机染料甲基蓝污染。即使PDMS@P25织布表面被有机染料尼罗红及亚甲基蓝等污染，在太阳光下仍可使其降解，实现表面的自清洁。该PDMS@P25织布具有良好的机械性能及重复使用性能，经100次摩擦后，其性能无明显变化，在10次循环使用后仍然具有稳定的光催化性能。该材料的制备工艺简单，原料均对环境友好，成本低廉，符合大规模生产的需要。

Abstract:
To develop environmentally friendly materials with efficient photocatalytic self-cleaning function， a composite coating was prepared by performing a photo-grafting reaction of polydimethylsiloxane （PDMS） and titanium dioxide （TiO2，P25） in ethyl acetate. This composite coating was then sprayed onto the fabric surface to obtain PDMS@P25 fabric. The influences of PDMS， TiO2， and ethyl acetate on superhydrophobicity of the PDMS@P25 fabric were investigated， and were characterized using contact angle measurements， scanning electron microscopy， transmission electron microscopy， and Raman spectroscopy. The ultraviolet （UV） degradation of the organic dye Nile red by the PDMS@P25 fabric was examined as well. The results show that after 60 minutes of UV irradiation， the PDMS@P25 fabric can completely degrade Nile red in water. At the same time， the PDMS@P25 fabric prevents its surface from being contaminated by sediment and organic dyes such as methyl blue in water. Even if the surface of PDMS@P25 fabric is contaminated with organic dyes like Nile red and methylene blue， it can still degrade the organic dyes under sunlight， showing a self-cleaning capability. The PDMS@P25 fabric exhibits excellent mechanical properties and reusability. Its performance remains unchanged even after 100 cycles of friction and maintains stable photocatalytic performance after 10 cycles of use. Moreover， the fabrication process of this material is simple， the raw materials are environmentally friendly， and the cost is low， making it suitable for large-scale production.
