  Intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant monomer having a functionality selected from the group consisting of a hydroxyl; a polyhydroxyl; an aromatic ring; a carbonyl; a carboxylic acid; a polycarboxylic acid; an aldehyde; a ketone; an amine; an amide; an ether; an ester; and mixtures thereof, 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.

  将层状材料（如叶硅酸盐）与具有以下功能性的插层单体接触而形成的插层物：羟基；多羟基；芳香环；羰基；羧酸；多羧酸；醛；酮；胺；酰胺；醚；酯；及其混合物。在相邻小板之间吸附足够的插层单体，使相邻小板的间距扩大到至少约 5 Å（在除水至最大 5%（重量）水分后测量），最大约 100 Å，最好在约 10-45 Å 的范围内，这样插层单体就很容易剥离成单个小板。插层复合物可与有机液体结合成粘稠的载体材料，用于载体材料的输送或活性化合物的输送；或者插层复合物可与基质聚合物结合，形成坚固的填充聚合物基质。
