Immobilization of imidazolium cation based ionic liquids on thin polymer films

Methods of gravimetry, optical microscopy, FTIR spectroscopy, and conductometry were applied to the study of the adsorption of the following ionic liquids: 1-butyl-3-methylimidazolium chloride, bistrifluoromethylsulfonylimide, and trifluoroacetate on thin-layer films of polymers of different nature including polypropylene, polyethylene terephthalate, polytetrafluoroethylene, poly(vinyl chloride), and hydrated cellulose. It was established that the hydrated cellulose film can serve as polymer matrices for the ionconducting 1-butyl-3-methylimidazolium halide salts. The hydrated cellulose additive in the ionic liquids promotes their immobilization on the poly(vinyl chloride) film.
