Melting intercalation method was successfully introduced in preparing PVC/OMMT nanocomposites.The dispersion state of organically modified montmorillonite(OMMT) and its mechanical and thermal properties in the PVC/OMMT nanocomposite system were studied with X-ray diffraction(XRD)
transmission electron microscopy(TEM).The results show that OMMT
stripping in the PVC matrix
can not only enhance the strength and toughness
but also improve the modulus in the appropriate amount of OMMT
nanocomposites have the best mechanics properties with 6 phr OMMT.OMMT can be in favor of the reduction of viscosity
but it will reduce the thermal decomposition temperature of PVC.
