Ultrasonic assisted fabrication of dual function surface on PET and preparation of single component ink to attain efficient self-cleaning function via digital printing

摘要

The self-cleaning effects of polyethylene terephthalate fabric (PET) through the photocatalytic effects of TiO2 (T), porphyrin (P) and silane (S) have been explored ultrasonically using bath type (WUC-D22H, Daihan Scientific, Korea). The ultrasonic power and frequency were 100 W and 30 kHz, respectively. The surface modification in fabric was achieved by the ultrasonic deposition of anatase TiO2 (T), porphyrin (P), and further modification by silane (S) was used to achieve dual-function (photocatalytic and superhydrophobic) self-cleaning behavior. The dye-degrading abilities of the modified fabric surface confirmed by the photo discoloration of various organic pollutants by visible light treatment. From the tested various dye, methylene blue (MB) decomposition was monitored using UV-Vis spectroscopy by measuring the changes in concentrations in the fabric at altered time breaks. The attachment of silane and its stability after washing the surface of fabric confirmed by measuring the water contact angle (WCA). The self-cleaning efficacies were in the order PET@TP > PET@TPS. The modifications are done in fabric surface characterized and confirmed by XRD, XPS, UV-Vis, and FESEM analyses. Fabric's self-cleaning effect examined with common daily life pollutants. Easy to make single-component ink prepared using silane (S) and used as digital printing ink and printed on fabric, exclusively attained hydrophobic surface in the printed area.
