The Effect of PVA and PEG Infusion on Titania Antibacterial Coating

Abstract

Indonesia has great potential of the Solar energy, irradiated by the Sun throughout the years. Cotton textiles antibacterial has been prepared by coating Titania (TiO2) with Polyethylene glycol (PEG) and Polyvinyl alcohol (PVA) as adhesives. The method of depositing cotton using a simple dip coating. Cotton dry for 15 minutes with a halogen lamp, after the deposition process. Then, we do the antibacterial activity test using Plate Count Method. As a result, the coated cotton textiles with Polyvinyl alcohol (PVA), Polyethylene glycol (PEG) has antibacterial properties. Characterization by the Attenuated Total Reflectance (ATR) obtained that Titania (TiO2) surely adhere on the sample. From Attenuated Total Reflectance (ATR) characterization we conclude that Polyvinyl alcohol (PVA) and Polyethylene glycol (PEG) is not affecting the antibacterial ability of Titania (TiO2). But the infusion of Polyvinyl alcohol (PVA) and Polyethylene glycol (PEG) on Cotton increases the stiffness value of Cotton.

The effect of TiO2 photocatalyst towards methylene blue degradation using simple dip coating

“…Line C and D show reduction in MB concentration due to the photocatalytic process of TiO2 catalysts. The catalytic degradation process in lines C and D is activated when a photon with higher energy than the MB band gap hits the surface, leaving a hole in the valence band [3,[6][7][8][9][10]. We find that both curves follow the pseudo-first-order decay kinetics with the irradiation time.…”

“…2). The catalytic degradation process in lines C and D is activated when a photon with higher energy than the MB band gap hits the surface, leaving a hole in the valence band [3,[6][7][8][9][10]. The fundamental principle of photocatalysis is illustrated in Figure 3.…”

“…Photocatalysts are important processes that provide a relatively simple means for converting solar energy, which is used in oxidation and reduction processes. There are myriad uses of photocatalysis: water and air purification, odor control, bacterial inactivation, inactivation of cancer cells, and many others [3][4][5][6][7][8][9]. Additionally, photocatalysis has been recognized as an environmentally safe method by providing breakthroughs that address environmental issues.…”
