摘　　要：通过电化学测试技术和失重法,研究了扩孔腐蚀过程中有机添加剂聚乙二醇(分子量为400)和乙二醇对铝箔比电容以及失重的影响,并在确定添加剂最佳用量的前提下,分析了温度对铝箔腐蚀的影响。研究表明,聚乙二醇和乙二醇最佳添加量分别为0.4,0.8g/L,铝箔比电容分别对应为372,334μF/cm2。经进一步优化发现,在聚乙二醇、乙二醇最佳添加量前提下,25℃时聚乙二醇与乙二醇扩容效果均达到最优,比电容分别达到449,489μF/cm2。The influences of polyethylene glycol and ethylene glycol on both specific capacitance and weight loss of the aluminum foil in the area enlarging corrosion procedure are investigated by the electrochemical technique and the weight loss measurement.The effect of temperature on this process is also studied.It is discovered that the optimal concentration of both additives in the etching solution is 0.4g/L for polyethylene glycol and 0.8g/L for ethylene glycol,and the specific capacitance of the obtained aluminum foils is corresponding to 372,334μF/cm2,respectively.Further experimental result shows that the most proper temperature is 25 ℃for the capacitance expansion of aluminum foil with 0.4g/L polyethylene glycol or 0.8g/L ethylene glycol,which can offer higher specific capacitance of 449,489μF/cm2,respectively.
