Polymer micelles composed of polystyrene‐ block ‐poly(methacrylic acid) have been chemically attached to amino‐modified SiO 2 surfaces by carbodiimide coupling. The density of coverage is very high (ca. 3 × 10 10 micelles/cm 2 ) and fairly uniform. The diameter of the micelles is ca. 50 nm and the distribution of micelle sizes is essentially undisturbed by this coupling reaction. These modified surfaces might be of interest in surface modification because of the very high density of reactive groups that are associated with each micelle.
