The present invention provides a polymeric adsorption film comprising a polymer containing two or more charge-transport blocks and a substrate, wherein any of the charge-transport blocks is preferentially adhered to a surface of the substrate; a polymeric adsorption film comprising a polymer containing two or more charge-transport blocks and a substrate, wherein any of the charge-transport blocks different from the charge-transport block preferentially adhered to a surface of the substrate is preferentially exposed; or a polymeric adsorption film comprising a polymer and a substrate, wherein the polymer contains two or more charge-transport blocks and any charge-transport block selected from the charge-transport blocks is adhered to a surface of the substrate more preferentially than the other charge-transport blocks.
