Abstract

The effect of anionic and cationic exchange polymer layer on the chronopotentiometry (CP) and current voltage curves (I-V) of charged composite membrane are investigated. Also, the ion transport near the interface between electrolyte and ionic exchange polymer membranes (anionic and cationic ones) and charged mosaic polymer composite membrane is studied. The results show that both anionic and cationic polymer exchange membranes exhibit lower voltage drop over range of applied current density and possess favorable industrial application potentials, especially at low KCl concentration. While the charged mosaic polymer composite membrane didn't show any current-voltage change, irrespective to the type and the concentration of used electrolyte. CP and I-V measurements are effectively used to give some fundamental understanding for ion transport behavior of ion exchange polymer membrane near the interlace.

크로노포텐시오미터(CP)와 전류-전압곡선(I-V)을 사용하여 음/양 이온 교환 층의 영향을 하전 모자이크 막에서 조사하였다. 역시 전해질과 음/양이온의 계면에서 이온수송을 실험하였다. 결과 음/양이온 교환 막은 전류범위에서 점점 전압강하가 나타났고, 특히 저 농도의 KCl 전위는 일정하였다. 한편 복합 하전 모자이크 막은 여러 전해질 수용액의 종류와 농도에 관계없이 전위의 변화는 없었다. CP와 I-V의 측정은 이온교환 막 계면에서 일어나는 이온수송에 대한 기초해석으로 대단히 유효하였다.
