Water on the surface of materials, within a range of several nanometers in thickness (referred to as interfacial water), plays a crucial role in various material properties such as wettability and resistance to protein adsorption. However, conventional methods have been unable to selectively analyze hydration structures and thickness of interfacial water. I evaluated the relationship between material properties, and hydration structures and thickness of interfacial water, through a combination of infrared spectroscopy and multivariate curve resolution.
In this presentation, I introduce applications of this analytical method to provide valuable insights on how this technique can be effectively utilized to advance materials development.
