In this study, self-cleaning polyester (PET) fabrics were prepared using TiOF and hexadecyltrimethoxysilane(HDS) treatment. TiOF was synthesized via direct fluorination of a precursor TiO at various reaction temperatures. The prepared PET fabrics had superior photocatalytic self-cleaning properties compared with anatase TiO/HDS-treated PET fabrics under UV and sunlight with 98% decomposition of methylene blue. TiOF/HDS-treated PET fabrics also had superior superhydrophobic self-cleaning properties compared with anatase TiO/HDS-treated PET fabrics with a 161° water contact angle and 6° roll-off angle. After the self-cleaning tests of the non-dyed TiOF/HDS-treated PET fabrics, we prepared dyed TiOF/HDS-treated PET fabrics to test practical aspects of the treatment method. These PET fabrics were barely stained by tomato ketchup; even when stained, they could be self-cleaned within 4 h. These results suggest that practical self-cleaning PET fabrics with superhydrophobicity and photocatalytic degradation could be prepared using TiOF/HDS-treatment.
在本研究中，采用TiOF和十六烷基三甲氧基硅烷（HDS）处理制备了自清洁聚酯（PET）织物。通过在不同反应温度下对前驱体TiO进行直接氟化合成了TiOF。与锐钛矿型TiO/HDS处理的PET织物相比，制备的PET织物在紫外线和阳光下具有优异的光催化自清洁性能，亚甲基蓝的分解率达98%。与锐钛矿型TiO/HDS处理的PET织物相比，TiOF/HDS处理的PET织物还具有优异的超疏水自清洁性能，其水接触角为161°，滚落角为6°。对未染色的TiOF/HDS处理的PET织物进行自清洁测试后，我们制备了染色的TiOF/HDS处理的PET织物，以测试该处理方法的实际应用方面。这些PET织物几乎不会被番茄酱弄脏；即使被弄脏，它们也能在4小时内实现自清洁。这些结果表明，采用TiOF/HDS处理可以制备出具有超疏水性和光催化降解性能的实用自清洁PET织物。
