Ionic liquids with discrete anions are deep eutectic solvents can be utilized for
metals electroplating. In this investigation various types of deep eutectic
solvents have been utilized such as Reline, Ethaline and Hybrid as solvents for
the electrodeposition of Sn, Zn and Zn-Sn alloys. Ethaline and Reline displayed
identical voltammetric profiles for the reduction of Zn+2 and Sn+2. Reline
possess high viscosity which lead to decreasing the quality of electroplating,
therefore the process needs higher temperature or longer electroplating time.
The surface morphology and compositions have been characterized using
scanning electron microscopy (SEM) and elemental analysis by energy
dispersive X-ray Spectroscopy (EDX). These techniques lead to detecting the
metal alloy that have been added to the ionic liquids. Pure ionic liquids
preparation was another aim of this investigation, which utilized as a standard
scale for comparison with the metal based liquids. Analysis of cyclic
voltammetry in all systems indicated differences in the reactivity and mobility of
species in solution which affected the growth mechanism and resulted in
changes in deposit morphology.
