Abstract
Hybrid nanocomposites based on organophillic montmorillonite (MMT) and ethylenepropylene-diene rubber (EPDM) have been prepared by a melt compounding process. From analysis by X-ray diffraction and transmission electron microscopy, the rubber molecules were found to be intercalated into the galleries of organoMMT and the silicate layers of organoMMT are uniformly dispersed as platelets of 50-80 nm thickness in the EPDM matrix. Dynamic mechanical studies reveal a strong rubber-filler interaction in the hybrid nanocomposite which is manifested in the lowering of tan delta at the glass transition temperature. The hybrid nanocomposites exhibit great improvement in tensile and tear strength, and modulus, as well as elongation-at-break. Moreover, the permeability of oxygen for the hybrid nanocomposite was reduced remarkably. (C) 2002 Society of Chemical Industry.
