The hydrophilic polymer brushes were prepared by surface-initiated ATRP of 2-methacryloyloxyethyl phosphorylcholine (MPC) and 2-(dimethylamino)ethyl methacrylate (DMAEMA) on the initiator-immobilized silicon wafer. Poly(DMAEMA) brush was treated with methyl iodide to give a cationic polymer brush. Water contact angles of the cationic brush and poly(MPC) brush were 39° and 5°, respectively. Frictional properties of these polyelectrolyte brushes were characterized by sliding a glass ball probe on the brush surfaces in air and water under the load of 0.49 N at a sliding rate of 90 mm/min. Friction coefficients of polymer brushes in water and humid air were lower than that in dry air. Further low friction coefficient was observed by sliding a glass ball immobilized with poly(MPC) brush on the surface of poly(MPC)-immobilized silicon wafer under humid air condition.
