We employed the pulsed field gradient nuclear magnetic resonance (PFG-NMR) technique to investigate the self-diffusion coefficient of water, $_{rm NMR}$ , in newly designed cation exchange membranes, made of sulfonated poly(-phenylene)-poly(ether ketone) multiblock copolymers, which are denoted by S-6H () :. The $_{rm NMR}$ value was measured as a function of the gradient strength, g, from 0.1 to 11.0 T/m. S-6H (14) 1:1 showed the $_{rm NMR}$ value about 10 times lower than the value in bulk liquid water. Small angle neutron scattering (SANS) measurements showed two peaks in S-6H (14) 1:1. The low peak is attributed to the formation of microdomains and the high peak is due to the formation of ionic clusters in the swollen microdomains.
