| Title: Intercalates And Exfoliates Formed With Hydroxyl-Functional, Polyhydroxyl-Functional, And Aromatic Compounds; Composite Materials Containing Same And Methods Of Modifying Rheology Therewith. |
Abstract: A method of producing Nanomers by contacting a layered material, e.g., a nanoclay, with a monomer having a hydroxyl and/or an aromatic ring functionality to sorb (intercalate) the monomer between adjacent nanoclay layers. Sufficient monomer is sorbed to expand them to a spacing of at least 100 Å, so that the Nanomer easily can be exfoliated into individual layers. The Nanomer can be combined with an organic liquid into a viscous carrier material, for delivery of the carrier, or for delivery of an active compound; or the Nanomer can be combined with a matrix polymer to form a nanocomposite. Alternatively, it can be exfoliated prior to or after combination with the organic liquid or the matrix polymer. combination with an organic liquid or the matrix polymer.
