[paper accepted] Hydration water in PEG- and PMPC-containing hydrogels

Hydration water governs the properties of hydrogels, but it is difficult to measure selectively in the presence of abundant bulk water. In this work, we applied our pressure-controlled ATR-IR spectroscopy combined with multivariate curve resolution (MCR) to hydrogels based on poly(2-hydroxyethyl methacrylate) containing PEG or PMPC, and selectively resolved the spectra of their hydration water.
