Poly(etherimide)/montmorillonite nanocomposites prepared by melt intercalation:morphology,solvent resistance properties and thermal properties

摘要

Polyirnide-MMT (montmorillonite) nanocomposites has been prepared by muck blending an organo-modifled MMT with a thermoplastic poly(etherimide) (PEI) in an internal mixer. The dispersion of the MMT layers wi~ the PEI matrix was verified using X-ray diffraction and transmission electron microscopy, revealing an exfoliation morphology. Owing ~*e molecular dispersion of the MMT layers and the strong iteraction between PEL and MMT, the nanocomposites exhibited a subs~~ ~ at glass transition temperature and thermal decom-psinirion temperature, and a dramatic decrease in solvent uptake comparde to the virgin PEI.
