Preparation and characterization of poly(ethylene oxide)/ montmorillonite intercalation compound

In this paper , poly(ethylene oxide) /montmorillonite intercalation compoun d was prepared through solution and melting intercalating, The intercalatio n compound was characterized by XRD, IR and DSC, etc. PEO molecule couold r eact with Na+ to form a coordination complex and it was in a spiral conform ation between montmorillonite layers, so the PEO molecule could not be extr acted by the solvent. As the molecular thermal action was restricted in the montmorillonite gallery , the melting peak of the PEO crystal in intercala tion compound was decreased.
