对Zn-PTFE(聚四氟乙烯)复合电极的复合电沉积过程进行研究，并考察了它在电合成频那醇上的应用.实验结果表明：控制镀液中PTFE悬浮量为30mL/L，镀液温度25℃，以5.0A/dm2电流密度电沉积22.5C，可制备出PTFE微粒分散均匀的复合电极；以此复合电极为阴极电合成频那醇，产率可达53.6%，明显高于Zn电极的25.1%.
A Zn-PTFE(Zinc-polytetrafluoroethylene) composite electrode withwell-dispersed PTFE fine particle has been prepared in conditions of 5.0 A/dm2, 22.5C, and PTFE 30 mL/L at 25 ℃. The composite electrode was used as cathode in electrosynthesis of pinacol from acetone in yield of 53.6%, much higher than that by using Zn electrode as cathode(25.1%).
