異方性導電薄膜環盤電極研究

Abstract

本論文研究異方性導電薄膜電極用於旋轉盤上，証明質量傳遞的實驗中旋轉盤電流與旋轉速率的平方根為線性關係，符合利用Levich方程式理論計算並我們研究異方性導電薄膜在環盤電極上經由溶液碘離子當擴散層經外加偏壓下由盤電極氧化成碘原子後，因旋轉離心力甩出由圓環還原為碘離子產生接收電流，算出收集比率。以證明異方性導電薄膜環盤電極可用於環盤電極的實驗當中。

This article reports ACF disc electrode for rde(rotating disc electrode) application. The experiment of the ACF electrodes show the mass transport-limited faradic current in the disk electrode is a linear function of the square root of rotation velocity. The diffusion coefficient of iodine was calculated form Levich equation. And we reports ACF films ring disc electrode. The disc electrode will oxidate iodine inside diffusion layer when voltage bias on electrode. When the electrode rotates, the iodide will go to the ring electrode.The ring electrode will reduce iodide.It will generates accepting current. Then we can calculate the collecting rate to show ACF ring disc electrode can work in RRDE (rotating ring disk electrode) experiment.
