研究室紹介
Professor Young-Nam Kwon's research lab specializes in advanced membrane science and environmental materials, focusing on the development and characterization of thin-film composite polyamide membranes for water treatment applications. The lab investigates membrane degradation mechanisms under oxidative conditions (e.g., chlorination and hypochlorite exposure), the adsorption behavior of emerging contaminants like perfluorinated compounds (PFCs), and innovative strategies to enhance membrane performance and durability—particularly through antiwetting surface engineering for membrane distillation. The research also addresses environmental challenges such as microplastic pollution from PPE waste, linking materials science with environmental sustainability.

15During the COVID-19 pandemic, the extensive use of face masks and protective personal equipment (PPE) kits has led to increasing degree of microplastic pollution (MP) because they are typically discarded into the seas, rivers, streets, and other parts of the environment. Currently, microplastic (MP) pollution has a negative impact on the environment because of high-level fragmentation. Typically, MP pollution can be detected by various techniques, such as microscopic analysis, density separation
Abstract A systematic investigation of the relationship between chlorine exposure of a thin film composite crosslinked polyamide membrane (LE membrane, FilmTec©) and changes in membrane performance (water flux and salt rejection) is discussed here. Performance change of crosslinked polyamide membranes due to chlorination depended on pH and concentration of chlorine in the soaking bath. Membranes chlorinated at low pH and high chlorine concentration showed flux decreases at an early stage of filt
