Intercalates formed by co-intercalation of monomer, oligomer or polymer intercalants and surface modifier intercalants and layered materials and nonocomposites prepared with the intercalates

InactiveUS6057396AEfficient intercalationIncrease spacingPaper coatingCoatingsEpoxyPolymer science
The present invention discloses intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant monomer surface modifier including an alkyl radical having at least 6 carbon atoms and a polymerizable monomer, oligomer or polymer. The intercalant monomer surface modifier converts the interlayer region of the layered materials from hydrophilic to hydrophobic, therefore, polymerizable monomers, oligomers or polymers can be easily intercalated into the interlayer spacing. The co-presence of the intercalant monomer surface modifier and polymerizable monomer, oligomer or polymer provide an environment for more polymerizable monomers, oligomers or polymers to be intercalated into the interlayer spacing and the intercalates are readily exfoliated into polymer matrices to form nanocomposites. The nanocomposites (e.g., epoxy-clay) prepared from the intercalates demonstrated enhanced mechanical, thermal and chemical resistance compared with pristine polymer matrices.
