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。

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%.
