Electrodeposition of aluminium from hydrophobic perfluoro-3-oxa-4,5 dichloro-pentan-sulphonate based ionic liquids

Aluminium electrodeposition from ionic liquids (ILs) prepared using a novel structure composed by perfluoro-3-oxa-4,5 dichloro-pentan-sulphonate [CF2ClCFClOCF2SO3-] and different cations is presented. The novel anion was designed by Solvay Specialty Polymers with the purpose to confer to the ionic l...
