HYBRID NANOSCALE PARTICLES |
摘要 |
<p>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: R1 and R2 are each independently H, or a (C1-C20)hydrocarbon group, R3 is a divalent (C1-C20)hydrocarbon group, R4 and R5 are each independently H or (C1-C2)alkyl, provided that R4 differs from R5, R6 is 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.</p> |
