POLYOXYETHYLENE INTERCALATION IN LAMELLAR COPPER IRON SULFIDE

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