Abstract (en)

[origin: WO2016193582A1] The invention concerns a method for controlling the surface energy at the top interface of a block copolymer (BPC1), the bottom interface of which is in contact with a previously neutralised surface of a substrate, so as to obtain an orientation of the nano-domains of said block copolymer (BPC1) perpendicular to the two bottom and top interfaces, said method consisting of covering the top surface of said block copolymer (BPC1) with a top surface neutralisation layer (TC), and being characterised in that said top surface neutralisation layer (TC) is constituted by a second block copolymer (BPC2).
