In this study, the fluorocarbon-hydrocarbon hybrid surfactant analogues of AOT was us ed for formation of emulsion between the aqueous solution and CO2. This surfactant has both 'CO2 philic' chain and 'hydrophilic' head group simultaneously, and research like formation of nano particle from metal was used synthesized. Prior to the electroplating in emulsion, the cloud point of this surfactant was measured and the microemulsion was formed in supercritical state. In addition, ‘microemulsion stability region’ was measured as measure-ment of cloud point in microemulsion. After then, electroplating of Ni on the surface of Cu was carried out in macroemulsion solution composed of CO2 and plating solution in supercritical state. The plating solution could be reduced to 1/3 times by this method. Qualities of plated ware can be evaluated by measuring thickness, uniformity, and corrosion resistance. Qualities such as corrosion resistance and uniformity of surface of plated ware obtained by this method were better than those by current method. |
