Abstract:
1. A particle treated with at least one fluorinated siloxane, the particle being at least 500 micrometers in size, wherein the fluorinated siloxane comprises a condensation product of at least one reactive fluorinated silane selected from the group consisting of: a polymeric fluorinated composition comprising: and at least one of or a chain-terminating group represented by the formula: a fluorinated urethane oligomer of at least two repeat units comprising: wherein Rf is a monovalent or multivalent perfluoroalkyl group optionally interrupted by at least one —O—; Rf each R is independently selected from the group consisting of alkyl having one to six carbon atoms and aryl; Q is a divalent or trivalent organic linking group containing from 1 to 4 functional groups selected from the group consisting of ester, amide, sulfonamide, carbonyl, carbonate, urea, and carbamate; each Y is independently selected from the group consisting of hydroxyl, alkoxy, acyloxy, and halogen; each R each W is independently selected from the group consisting of alkylene, arylalkylene, and arylene, wherein alkylene is optionally interrupted or substituted by at least one heteroatom; each X is independently selected from the group consisting of —NH—, —O—, and —S—; X Z is a divalent organic linking group; x is 0, 1, or 2; y is 1 or 2; and z is 1, 2, 3, or 4.
