The present 34 months project proposal deals with  synthesis, characterization and application of certain types  of  ionic liquids (fluid liquids at temperatures under 100⁰C) as environmentally friendly  electrolytes to perform some surface treatments of high performance with  applications in different industrial areas as electronic industry, electrical engineering, machine building industry, autovehicles domain. With this in  view, experimental activities are concentrated on investigation of ionic liquid medium based on choline chloride(2 hidroxy – ethyl-thrimethyl ammonium) and urea (NH₂C=ONH₂), characterized by a minimum impact on environment, that is recyclable, biodegradable and non-toxic, that has proved to be an attractive electrolyte for applications in galvanotechnics, respectively for electrodeposition of pure metals and alloys, electropolishing of stainless steel and valve metals  (Al, Ti, Ta).

Thus the following issues are taken into consideration:

(i) synthesis, physical-chemical and electrochemical characterization of some ionic liquids based on choline chloride as a base for  electrolytes preparation used in electrochemical electrodeposition processes of metallic coatings with functional and protective characteristics (Ni, Cu, Sn, Ag, Al, V and their alloys) with applications in electrical engineering, electronic industries (in fabrication flows of PCBs) and in electropolishing  of metallic surfaces of stainless steel, Al, Ti;

(ii) evaluation, testing and validation of the new elaborated technologies with demonstration of functionality including their use on technological flows of PCBs.

The main advantage of the development and promotion of the use of these new electrochemical media refers not only at the accumulation of new  scientific information (this is a relatively new domain that proved new possibilities in the last five years) but also allows the minimization of production costs, of industrial waste quantities, with positive effects on environment and health.
