Abstract

Abstract: TMPAC-AlCl₃ ionic liquids with different molar ratios of TMPAC and AlCl₃ were synthesized,and their conductivities were measured at different temperatures.The study was performed by means of constant current electrolysis,and the effects of temperature,current density,stirring speed and toluene additive amount on the deposited aluminum layers were investigated.Conductivity of TMPAC-AlCl₃ ionic liquids reached a maximum with 1:2 molar ratio of TMPAC to AlCl₃ at 80℃. Better quality deposit and higher current efficiency could be achieved at the same temperature with current density of 20 mA·cm^-2 and stirring speed of 500 r·min^-1.Conductivity of the ionic liquid increased but voltage of the electrolytic cell decreased with the addition of toluene.A dense,bright,smooth and uniformly distributed deposit was obtained at current density of 23 mA·cm^-2 when volume percent of toluene was 50%.

Key words: aluminum, electrodeposition, ionic liquid, conductivity, toluene

摘要： 合成了不同TMPAC和AlCl₃摩尔比的TMPAC-AlCl₃离子液体,并测定了其在不同温度下的电导率。在摩尔比为1:2的TMPAC-AlCl₃离子液体中进行了恒电流电沉积实验,研究了温度、电流密度、搅拌速度和添加剂甲苯等对沉积层的影响。结果表明:在相同条件下摩尔比为1:2的TMPAC-AlCl₃离子液体电导率最大,当温度为80℃,电流密度为20 mA·cm^-2,搅拌速度为500 r·min^-1时,沉积层质量较好且电流效率较高;甲苯的加入,增大了TMPAC-2AlCl₃离子液体的电导率,降低了槽电压,当添加甲苯的体积分数为50%,电流密度为23 mA·cm^-2时,可以得到较为致密、色泽良好、平整而均匀的沉积层。
