Effect of Water on the Size Distribution of Free-Volume Holes in Nafion Membrane
Original language description
Positron lifetime spectroscopy was employed for investigation of the size distribution of free volume holes in Nafion N-1110 membrane. Size distribution of free volume holes was determined in the as-received and dried membrane and in the membrane immersed in water at various temperatures. It was found that absorbed water causes reduction of the mean size of free volume holes and increase of their dispersion and concentration. This indicates that free volumes are split by swollen ionic clusters absorbingwater. The kinetics of water uptake and the amount of absorbed solvent were determined by in-situ measurement of the weight increase.
