1. A method for modifying a surface of a polymer substrate, the method comprising:
treating the surface of the polymer substrate with plasma;
applying a hydrophilic primer, under a wet process, comprising a polymer of aminoalkylsilane and a first functional organic or inorganic silane compound onto the surface of the plasma-treated polymer substrate; and
hydrophobic coating the plasma-treated polymer substrate with a coating agent, under a wet process, containing a hydrophobic fluorine compound in a fluorine-based solvent comprising a condensed polymer of a fluorine-based polymer and a second functional organic or inorganic silane compound,
wherein at least one of the first functional organic or inorganic silane compound and the second functional organic or inorganic silane compound is at least one compound selected from the group consisting of phenylaminopropyltrimethoxysilane, γ-aminopropyldimethoxysilane, γ-aminopropyldiethoxysilane, chlorotrimethylsilane, trichloroethylsilane, trichloromethylsilane, trichlorophenylsilane, trifluoropropyltrimethoxysilane, bis(trimethoxysilylpropyl)amine, bis(3-triethoxysilylpropyl)tetrasulfide, bis(triethoxysilylpropyl)disulfide, and p-styryltrimethoxysilane.
