【研究の概要】

In line with the goals of SDG 6 – Clean Water and Sanitation, our research endeavors to engineer surfaces endowed with anti-fouling properties. While it is widely recognized that employing the LST technique on a surface can lead to an increase in the surface area exposed to bacterial adhesion, applying a specific type of coating has been shown to notably reduce bacterial growth. Recent advances in coating materials have demonstrated the effectiveness of Zinc Oxide (ZnO), an inorganic compound, as an antibacterial agent. Furthermore, through the LST technique, it is possible to modify a contact surface to possess superior wettability properties, exerting an additional influence on bacterial adhesion and growth. Thus, the integration of the LST technique with a ZnO/TiO₂ coating presents a promising approach to cope with fouling issues. By combining LST technique with coating technologies, one can achieve enhanced hydrophobic and oleophobic characteristics by generating nano/micro surface textures on water pipelines, creating self-cleaning characteristics.

【将来の発展性】

This research aims to generate a graphical wettability map, considering various surface textures characterized by their intensity, shapes, and sizes. The objective is to offer innovative avenues for crafting surface texture designs and coating materials that can substantially augment wettability properties, particularly for applications in self-cleaning and anti-fouling. The expertise gained from this endeavor will be applied in water pipelines, ultimately bolstering access to clean water in developing nations.
