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 and having a dipole moment greater than the dipole moment of water, to sorb or intercalate the intercalant monomer between adjacent platelets of the layered material. Sufficient intercalantt monomer is sorbed between adjacent platelets to expand the adjacent platelets to a spacing of at least about 5 A (as measured after water removal to a maximum of 5 percent by weight water), up to about 100 A and preferably in the range of about 10-45 A, 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. |
