Patent ID: 8048525

Claim:
An adsorption method, comprising adsorbing a monolayer of 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 particle core having an outer surface, and (b) an organic layer disposed on at least a portion of the surface of the inorganic particle core and comprising one or more phosphonates according to structure (I): wherein: R 1 and R 2 are each independently H, or a (C 1 -C 20 )hydrocarbon group, R 3 is a divalent (C 1 -C 20 )hydrocarbon group, R 4 and R 5 are each independently H or (C 1 -C 2 )alkyl, provided that R 4 differs from R 5 , R 6 is H or a (C 1 -C 30 )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, wherein the nanoscale inorganic particle core consists of a single nanoscale inorganic particle, respectively.
