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%.
