Disclosed are pellicular materials useful in contact with proteins and as chromatography media. Rigid, inert, hydrophobic, polymeric materials are exposed to a solution comprising a solute defining plural interspersed hydrophobic and hydrophilic domains. The solute molecules adsorb onto the surface of the substrate by hydrophobic - hydrophobic interaction with their hydrophilic domains extending outwardly away from the surface into the solution. The molecules are then crosslinked in place to produce a solvent and pH resistant coating which presents a hydrophilic surface sufficient to mask hydrophobic regions therebeneath. The multidomain adsorbing compounds may comprise reactive groups which subsequently can be derivatized using conventional techniques to produce chromatography materials useful for conducting affinity, size exclusion, cationic exchange, anionic exchange, neutral hydrophobic interaction, and other forms of chromatographic separations.
