乙二醇在电沉积中的应用

The application of ethylene glycol in electrodeposition

纯乙二醇(EG)和乙二醇-离子液体(EG-ILs)作为电解液在电沉积中进行了大量的应用。对EG体系中电沉积半导体材料、热电材料和金属单质进行总结,发现EG作为有机溶剂,具有较高的沸点而适合较大范围温度下的电沉积,电沉积温度从高温往室温发展,能通过添加剂和工艺参数对镀层进行调控。对EG-ILs体系中电沉积磁性材料、耐蚀材料和催化材料进行总结,发现在EG-ILs中电沉积得到镀层材料的耐腐蚀和催化性能优异。综述了金属在EG镀液中的电沉积机理。

Ethylene glycol(EG)and ethylene glycol-ionic liquids(EG-ILs)have found extensive applications as electrolytes in electrodeposition.A comprehensive overview of semiconductor materials,thermoelectric materials,and elemental metals electrodeposited in the EG system reveals EG's effectiveness as an organic solvent due to its high boiling point,making it suitable for electrodeposition across a broad temperature range.The evolution of electrodeposition temperatures from high to ambient temperatures and the ability to finely control coating properties through additives and process parameters are notable aspects.In the EG-ILs system,a summary of electrodeposited magnetic materials,corrosion-resistant materials,and catalytic materials demonstrates that coatings obtained in EG-ILs exhibit outstanding corrosion resistance and catalytic performance.This review also delves into the electrodeposition mechanism of metals in EG plating solutions.
