Intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant surface modifier selected from the group consisting of a compound having an alkyl radical containing at least 6 carbon atoms, a compound containing an aromatic ring, and mixtures thereof, said surface modifier including a matrix material-reactive functional group, to sorb or intercalate the intercalant surface modifier between adjacent platelets of the layered material. Sufficient intercalant surface modifier is sorbed between adjacent platelets to expand the adjacent platelets to at least about 10 .ANG., up to about 100 .ANG.. 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.
通过将层状材料(例如
云母石)与表面改性剂接触,形成夹层化合物。所述表面改性剂选自具有至少6个碳原子的烷基基团的化合物,含有芳香环的化合物和其混合物,该表面改性剂包括与基质材料反应的功能性基团,以吸附或夹层化合物表面改性剂在层状材料的相邻板层之间。足够的夹层化合物表面改性剂被吸附在相邻板层之间,将相邻板层扩展至至少10 ANG,最高可达100 ANG。夹层化合物可以与有机液体混合成粘稠的载体材料,用于传递载体材料或活性化合物;或者将夹层化合物与基质聚合物混合形成强度高的填充聚合物基质。
