Development of a novel method for preparing functional films by two-liquid-phase interface electrodeposition

已知在含有金属离子的水溶液和不混溶的有机液体之间的界面处的电解导致叶状沉积物沿着界面生长。我们最近发现了金属薄膜的生长，如锌、钴，etc.in一定的实验条件下。因此，作为该方法的一个应用，将有望制备新的功能薄膜，从这个角度出发，本课题的研究目的是发展该方法，向金属和有机薄膜的新制备方法发起挑战，以建立双液相界面电沉积法作为功能薄膜的制备方法。在1996财政年度，我们研究了影响阴极还原法制备金属膜的几个因素，并成功地制备了金膜。在1997年度，我们尝试了用阳极氧化法制备导电有机薄膜，并成功地制备了聚吡咯薄膜。此外，我们还制作了计算机控制的设备来执行薄膜沉积物的连续生长。结果表明，该方法是一种很有前途的制备连续薄膜导电材料的方法。

It is known that the electrolysis at the interface between an aqueous solution containing metallic ions and an immiscible organic liquid results in the growth of leaf-like deposits along the interface. We found recently film growth of metals, such as zinc, cobalt, etc.in the certain experimental conditions. Therefore, as an application of this method, it will be expected to prepare new funcrional films.From this point of view, the purpose of this research project is to develop this method and to challenge to new preparations of metallic and organic films, in order to establish the two-liquid-phase interface electrodeposition method as a preparation method of functional films. In 1996 fiscal year, we investigated several factors governing the preparation of metallic films by cathodic reduction, and succeeded in preparation of gold films. In 1997 fiscal year, we tried to prepare conducting organic films by anodic oxidation, and succeeded in preparation of polypyrrole films. And also, we made computer-controlled apparatus to perform continuous growth of filmy deposits. From these results, it is confirmed that this method is to be a promising noble method to obtain continuously filmy conductint materials.
