Polyoxyethylene intercalation in lamellar copper iron sulfide

The insertion of polyethyleneoxide in a lamellar copper iron sulfide of formula CuFeS2 by an exchange reaction of potassium from KCuFeS2 with an aqueous solution of the polymer was performed. The characterization of the new compound by X-ray diffraction and IR absorption spectroscopy shows that the layer structure of the precursor has been retained and that the polymer adopts a zigzag configuration between the layers.
