Close hydrodynamic interaction between a hydrophilic body and a hydrophobic one is studied theoretically. The role of hydrophoby is manifested in the slipping of a liquid past a solid surface. An expression obtained in the work links together the force of hydrodynamic resistance, the thickness of the slit, the approach velocity, and characteristics of the interacting bodies. The possibility of applying the results to various problems of colloidal chemistry is discussed.
