초록

In this study, visible light responded photo catalysts and silane polymers were applied to PET fabrics to occur photoreaction and super hydrophobic property. First, TiO2 doped with Ag metal ions was prepared, and the Ag-doped TiO2 was combined with AgI, WO3, and ZnO photocatalysts. Because photodegradation properties are improved by complexing photocatalysts. And they were treated on PET fabrics to occur a self-cleaning function. Ag ions reduce the bandgap energy of TiO2 so that it exhibits excellent photodegradation under visible light. In addition, WO3, ZnO, and AgI have improved electron mobility through synergy with Ag ions present in the metal-doped photocatalyst. In addition, by applying a silane polymer to PET fabrics, super hydrophobic properties are realized on the surface of fiber. SEM, EDS, and XRD were used to evaluate the properties and performance of the visible light responsive photocatalysts. Contact angles were measured to evaluate the properties of the silane-treated fabric surface. As a result, PET fabric realizes excellent initial photodecomposition rate that decompose more than 90% of Methylene blue in 4 hours, and super hydrophobic property of contact angle 165 °. If there are further studies, the possibility of self-cleaning functional fibers will be high.
