A visible-light sensitized, superhydrophobic, self-cleaning Polyethylene terephthalate (PET) fabric exhibiting photocatalytic dye degrading properties has been prepared by depositing anatase TiO₂, porphyrin (TPPS, CuTPPS), and trimethoxy(octadecyl)silane (Si) onto the PET samples. The modified PET fabric showed superhydrophobicity, exhibiting a water contact angle (WCA) of 147°, and the ability to photodegrade rhodamine dye (RB), and the dye degradation ability of the modified fabric under visible light was monitored at different time intervals by UV–Vis spectroscopy. The degradation efficiency was found to be in the order PET/TiO₂/TPPS > PET/TiO₂/TPPS/Si > PET/TiO₂/CuTPPS > PET/TiO₂/CuTPPS/Si > PET/TiO₂ > PET. The photodegradation ability and superhydrophobicity of the modified PET samples in relation to coffee and ketchup stains were examined qualitatively. Due to its superhydrophobicity, water soluble impurities/coffee drops roll off the surface of the modified PET fabrics, resulting in stain-free fabric. The fabrics were characterized by UV–Vis, FESEM, XRD and XPS. The structures of the synthesized porphyrin and TiO₂ were confirmed by ¹H NMR spectroscopy and XRD analysis, respectively.

通过将锐钛矿型TiO ₂，卟啉（TPPS，CuTPPS）和三甲氧基（十八烷基）硅烷（Si）沉积到PET上，制备了具有光催化染料降解性能的可见光敏化，超疏水，自清洁的聚对苯二甲酸乙二醇酯（PET）织物。样品。改性PET织物表现出超疏水性，水接触角（WCA）为147°，并且具有光降解罗丹明染料（RB）的能力，并且在不同的时间间隔内通过紫外光监测改性织物在可见光下的染料降解能力。 –可见光谱。发现降解效率按以下顺序排列：PET / TiO ₂ / TPPS> PET / TiO ₂ / TPPS / Si> PET / TiO ₂ / CuTPPS> PET / TiO ₂ / CuTPPS / Si> PET / TiO₂  > PET。定性地研究了改性PET样品相对于咖啡和番茄酱污渍的光降解能力和超疏水性。由于其超疏水性，水溶性杂质/咖啡滴会从改性PET织物的表面滚落下来，从而形成无污染的织物。织物的特征在于紫外可见，FESEM，XRD和XPS。分别通过¹ H NMR光谱和XRD分析确认了合成的卟啉和TiO ₂的结构。
