ABSTRACT:
Disclosed are hydrophilic coatings covalently bound to hydrophobic surfaces as well as methods for their production. To form the coated surfaces, a compound is provided which comprises a hydrophobic domain including an unsaturated group and a hydrophilic domain. Also provided is a hydrophobic surface comprising unsaturated groups. Molecules of the compound are adsorbed onto the hydrophobic surface, and the unsaturated groups in the hydrophobic domains of molecules of the compound then are covalently crosslinked to the unsaturated groups on the hydrophobic surface by a free radical reaction. In one embodiment, hydrophilic coatings may be covalently attached to hydrophobic polymers such as divinylbenzene crosslinked polystyrene. Hydrophilic coatings covalently attached to hydrophobic surfaces are obtained which are stable, which may be readily derivatized, and which are useful in a wide range of chromatography applications.
