ABSTRACT:
An adsorption method includes the step of adsorbing hybrid particles from a colloidal dispersion of such particles at an interface between the dispersion and a second phase, said hybrid particles comprising:(a) a nanoscale inorganic core having an outer surface, and(b) an organic layer disposed on at least a portion of the surface of the inorganic core and comprising one or more phosphonates according to structure (I):wherein:R1and R2are each independently H, or a (C1-C20)hydrocarbon group,R3is a divalent (C1-C20)hydrocarbon group,R4and R5are each independently H or (C1-C2)alkyl, provided that R4differs from R5,R6is H or a (C1-C30)hydrocarbon group,m and n are each independently integers of from 0 to about 200, provided that the sum of m+n is at least 1.
