Research Topics

To protect public health and promote sustainability, our society needs advanced air filtration materials that efficiently capture airborne viruses and fine particles while minimizing energy use. This project explores the potential of bio-sourced, biodegradable polymers—such as polylactic acid (PLA)—as eco-friendly alternatives for high-performance filters. We have been  developing melt-blown techniques for these green materials, focusing on the key factors that influence nonwoven performance, with the goal of creating effective, biodegradable air filtration media.
