Intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant monomer including an alkyl radical having at least 10 carbon atoms to sorb or intercalate the intercalant monomer between adjacent platelets of the layered material. Sufficient intercalant monomer is sorbed between adjacent platelets to expand the adjacent platelets to a spacing of at least about 5 Å (as measured after water removal to a maximum of 5% by weight water), up to about 100 Å and preferably in the range of about 10-45 Å, so that the intercalate easily can be exfoliated into individual platelets. The intercalated complex can be combined with an organic liquid into a viscous carrier material, for delivery of the carrier material, or for delivery of an active compound; or the intercalated complex can be combined with a matrix polymer to form a strong, filled polymer matrix.

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.
