Abstract:
A method of manufacturing a chemically adsorbed film comprising:(1) providing a substrate surface, wherein said surface comprises active hydrogens or an alkali metal, and contacting said surface with chemical admolecules, wherein said admolecules contain functional groups shown in formula [A] or formula [B];promoting a dehydrochlorination or alcohol elimination reaction, thereby covalently bonding said chemical admolecules to the substrate;removing unreacted chemical admolecules;reacting the substrate surface with water and substituting one or more members of the group consisting of a halogen group and an alkoxyl group with a hydroxyl group; whereinFormula [A] comprises the designation--AXmwhere X represents a halogen, A represents Si, Ge, Sn, Ti, Zr, S or C, and m represents 2 or 3; and whereinFormula [B] comprises the designation--A(Q)mwhere Q represents an alkoxyl group, A represents Si, Ge, Sn, Ti, Zr, S or C, and m represents 2 or 3; and(2) contacting said substrate surface with chemical admolecules containing at least one functional group selected from the group consisting of formulas [C], [D], [E], [F] and [G], thereby promoting a dehydrochlorination, water elimination or alcohol elimination reaction,and removing unreacted chemical admolecules and reacting the substrate surface with water; whereinFormula [C] comprises the designation--AX.sub.nwhere X represents a halogen, A represents Si, Ge, Sn, Ti, Zr, S or C, and n represents 1, 2 or 3; and whereinFormula [D] comprises the designation--A(Q).sub.nwhere Q represents an alkoxyl group, A represents Si, Ge, Sn, Ti, Zr, S or C, and n represents 1, 2 or 3; and whereinFormula [E] comprises the designation--SO.sub.2 Xwhere X represents a halogen; and whereinFormula [F] comprises the designation--SOXwhere X represents a halogen; and whereinFormula [G] comprises the designation>N--CHO or --OCHOthus forming the chemically adsorbed film.
