摘要:
Nanocomposites are manufactured by combining a matrix polymer and exfoliated intercalates formed by contacting a phyllosilicate with a water-insoluble polymer to adsorb or intercalate the polymer between adjacent phyllosilicate platelets. Sufficient water-insoluble polymer is adsorbed between adjacent phyllosilicate platelets to expand the adjacent platelets to a spacing of at least about 10 .ANG. (as measured after water removal), up to about 100 .ANG. and preferably in the range of about 30-40 .ANG., so that the intercalate easily can be exfoliated, e.g., when mixed with a polymer melt, to provide a matrix polymer/platelet composite (nanocomposite) material--the platelets being exfoliated from the intercalate.
