空心聚苯乙烯微球电沉积金工艺

采用自行设计的微球电沉积装置, 建立了空心聚苯乙烯(PS)微球的电化学沉积金工艺。实验条件为：电源输出电压0.7~0.8 V, 电流密度2.0 mA·cm－2, 镀液温度45 ℃, 阴极转速250 r·min－1, 镀液流速7 mL·min－1·cm－2。在此工艺条件下制得的空心金微球对称性和厚度均匀性良好, 表面粗糙度低于500 nm, 微球表面沉积金速率约为6 μm·h－1。

Abstract

Using the self-regulating new micro-sphere electrodepositing device, the techniques of electrodepositing gold on hollow PS micro-spheres were established. The experiment was carried out under the following conditions：voltage was about 0.7~0.8 V, current density was 2.0 mA·cm－2, the temperature was 45 ℃, cathode rotating rate was 250 r·min－1, flow rate of the solution was 7 mL·min－1·cm－2. Hollow gold-plated micro-spheres were prepared with well spherical symmetr, uniform thickness and surface smoothness under 500 nm. The speed of the gold depositing was 6 μm·h－1.
