Abstract

Self-cleaning fabrics decorated with titanium dioxide (TiO2) nanoparticles (NPs) have garnered worldwide attention due to their outstanding ultraviolet (UV) light-shielding, anti-bacterial properties and other characteristics. Numerous techniques to construct super-antiwetting surfaces have been investigated for both fundamental research and practical application. A facile and eco-friendly way by a combination of UV irradiation and ultrasonic bath method has been developed to prepare a novel self-cleaning hybrid polyamine 6/nano TiO2 (PA6/nano TiO2) fabric with superhydrophobic and durable photocatalytic properties. To evaluate the fabric's reusability, hybrid PA6/nano TiO2 fabrics were subjected to five consecutive cycles of the photocatalytic degradation of the methyl orange (MO) dye. The results indicated that TiO2 NPs were firmly fixed on the fiber surface. The UV-blocking and anti-microbial properties of these hybrid fabrics were also tested. For PA6 immobilized by commercial nano TiO2-P25 (P25-PA6) and PA6 immobilized by prepared visible-light photocatalyst PVAD-TiO2(PVAD-PA6) fabrics, the UV protection factors (UPFs) of the samples were 56 and 1123, respectively. The anti-microbial efficacies of the two samples were both 99%. The water contact angles were 151.7° and 154.6°, respectively, indicating surface superhydrophobicity. These results showed that this novel fabric has great potential for indoor environmental purification and outdoor protection applications.
