Nuclear magnetic resonance studies of water in disperse systems

The nuclear magnetic resonance relaxation times of water protons in aqueous suspensions of polystyrene lattices and in lamellar mesomorphic phases have been measured. The results indicate that the surfaces examined have no long range effect on water structure. The main effect is the binding of water molecules to charged surface groups though an additional effect occurs when pores are formed by flocculation of the polystyrene spheres or when the lamellar phase contains water layers less than 20 A thick.
