A method of exfoliating a layered silicate comprising:
mixing from about 0.1 to about 100 weight parts of an intercalated layered silicate with 100 weight parts of a matrix medium to form a mixture, wherein:
the intercalated layered silicate comprises:
a layered silicate comprising a plurality of silicate layers; and
an intercalating agent sorbed between the silicate layers in an amount effective to provide an average interlayer spacing between the silicate layers of at least about 20Å, wherein the intercalating agent is selected from one or more of fatty acid esters of sorbitan, fatty acid esters of glycerol, fatty acid amide waxes, variants of amide waxes, and variants of amides; and
the matrix medium comprises one or more materials selected from:
polymer selected from one or more of ethylene/vinyl alcohol copolymer, ionomer, vinyl plastic, polyamide, polyester, and polystyrene;
energy curable polymer precursors;
coating solvents, coating binders, and coating resins;
ink solvents and ink resins;
grease lubricating oils and grease gelling agents;
cosmetic lipids, cosmetic emollients, cosmetic humectants, cosmetic film formers, cosmetic binders, cosmetic surfactants, and cosmetic solvents;
pharmaceutical excipients;
emulsions selected from an oil-in-water emulsion and a water-in-oil emulsion; and
adding sufficient energy to the mixture to form a dispersed-particle composition comprising at least about 0.1 weight parts exfoliated particles per 100 weight parts matrix medium.
