| Outline of Final Research Achievements |
In order to understand the interfacial structure changes between biomaterials and contacting solutions induced by pH variation, pH-dependent infrared spectra of polymer film in contact with aqueous solution were measured. A series of the obtained spectra was analyzed by means of perturbation-correlation moving-window two-dimensional (PCMW2D) correlation method. Both structure changes in the hydrated polymer chains and hydrating water molecules induced by the pH variation were revealed in the present study.
