Spectroscopic evidence of phase transition of monomolecular water in solid polystyrene.
Phase transition behavior of monomolecular water in solid polystyrene was examined by temperature variable Fourier transform infrared spectroscopy. Spectral changes showed for the first time that monomolecular water in a polymer matrix (in a closed system) could be condensed and then frozen and also that the ice formed could be grown and diminished by vapor deposition in cooling process and sublimation in heating process, respectively.
