Abstract

It is shown that swelling of an initially hydrophobic Nafion plate in a cell of limited volume follows a different way in ordinary water (deuterium concentration 157 ppm) and in deuterium-depleted water (deuterium concentration 1 ppm). Small variations in the deuterium concentration in water turn out to lead to a considerable difference in swelling dynamics of the polymer membrane. For a Nafion plate 175 µm thick, this effect is most distinct at the distance between the windows L = 200 µm.

聚合物膜在水中溶胀的流变效应及其对同位素组成的依赖性

摘要

结果表明，在普通水（氘浓度为157 ppm）和贫氘水中（氘浓度为1 ppm）中，初始疏水的Nafion板在有限体积的电池中的溶胀以不同的方式发生。水中氘浓度的细微变化最终导致聚合物膜溶胀动力学的显着差异。对于厚度为175 µm的Nafion板，这种效果在窗口L = 200 µm之间的距离处最为明显。
