The states of water in membranes of PMEA and PHEMA were studied with solution 2H-NMR method. The membranes were prepared by spin-coating on PET film. In order to investigate the change in the behavior of water with time after adding of H2O in membranes of PMEA and PHEMA, 2H-NMR measurements were carried out. From the results of the time dependence spectra and spin-lattice relaxation time T1, the followings were concluded. The mobility of water molecule in the PMEA membrane after H2O addition was higher than that in the PHEMA membrane, while exchange rates of the water between inside and outside of the PMEA membrane were slower than those of the PHEMA membrane. The state of water structure in the PMEA membrane is more stable than that in the PHEMA membrane.
