| Abstract |
A super-hydrophobic PET fabric exhibiting photocatalytic self-cleaning properties under visible-light was prepared by step-wise deposition of anatase TiO2, 2 types of porphyrin and trimethoxy(octadecyl)silane (OTMS). The modified PET (TSPP/TiO2/OTMS) / (CuTSPP/TiO2/OTMS) fabrics not only exhibited excellent super-hydrophobicity with a water contact angle of 148o, but also showed significant photocatalytic degradation of rhodamine-6G under visible-light irradiation. The fabrics were characterized by FESEM, XRD, NMR and UV-Vis spectroscopy. Textiles with dual functionality of super-hydrophobicity and visible light photo catalysis are promising for a wide range of self-cleaning applications. CuTSPP/TiO2-coated PET fabrics showed superior self-cleaning performance when compared to bare TiO2-coated PET. Furthermore, CuTCPP/TiO2/OTMS -coated fabrics showed significant photo stability and self-cleaning property under visible-light as compared to free base TSPP/TiO2/OTMS -coated fabrics, however the super-hydrophobic property is higher for TSPP/TiO2/OTMS when compared to that of CuTCPP/TiO2/OTMS. Visible-light driven self-cleaning PET based on porphyrin/TiO2/OTMS catalyst exhibits significant potential in terms of stability and reproducibility for self-cleaning applications. |
