PURPOSE:To provide a monomolecular film enhanced in hydrophilicity by chemically bonding a chemical adsorbing monomolecular film containing a hydrophilic group to a base material by a siloxane bond. CONSTITUTION:A hydrophilic base material is prepared to be well washed and subsequently brought into contact with a non-aqueous solvent mixed with a substance having a chlorosilyl group at its molecular terminal, for example, compound A-(B)l-SiXqCl3-q (wherein A is a bromo group, a iodo group, a cyano group, a thiocyano group, a chlorosilyl group or a functional group containing an ester bond, q is 0, 1 or 2, l is an integer of 1-30 and B is an org. group) and the hydroxyl group on the surface of the base material is reacted with the chlorosilyl group of the substance containing the chlorosilyl group at its molecular terminal to form a chemical adsorbing film and, thereafter, the surface of the film is substituted with a hydrophilic group. |
