Poly (ethylene oxide)/montmorillonite nanocopmosite hybrids were prepared by melt intercalation. The X-ray diffraction patterns showed that the layered spacing enlarged from 2.52 nm(for pure montmorillonite) to 3.94 nm for hybrid and the diffraction intensity of crystalline PEO was decreased. The DSC results exhibited a great decrease of the PEO/montmorillonite, implying that PEO molecules are easily intercalated into the layered montmorllonite. Thus, the low crystallinity in composite products is caused by the confinement of PEO molecule motion between the montmorillonite layers. The intercalating mechansim between PEO and montmorillonite has been discussed briefly.
