摘要
Disclosed herein is a method of evaluating the performance of an ion-exchange film. In the method, small-angle scattering curves for the ion-exchange film at different humidities are obtained by an X-ray measuring apparatus that can detect X-rays scattered at small angles with respect to the axis of an X-ray applied to the ion-exchange film. From the positions of the peaks on the small-angle scattering curves and the X-ray intensities at these peaks, the change in the characteristic of the film, which accompanies change in the molecular structure (hence, ion-exchanging ability) of the ion-exchange film due to the change in humidity, is evaluated. The humidity ambient to the ion-exchange film can be adjusted by a humidity-adjusting device that comprises a vapor source, gas source, gas mixer and gas-introducing pipe.
