摘要： The invention relates to a process for controlling the surface energy at the upper interface of a block copolymer (BCP1), the lower interface of which is in contact with a preneutralized surface of a substrate, in order to make it possible to obtain an orientation of the nanodomains of the block copolymer (BCP1) perpendicularly to the two lower and upper interfaces, the said process consisting in covering the upper surface of the block copolymer (BCP1) with an upper surface neutralization layer (TC) and being characterized in that the said upper surface neutralization layer (TC) comprises a second block copolymer (BCP2).

摘要： A copolymer including units derived from fluoro monomers of formula (I): CX1X2═CX3X4  (I) in which each of the X1, X2, X3 and X4 is independently chosen from H, F and alkyl groups including from 1 to 3 carbon atoms which are optionally partially or totally fluorinated, the H and/or F atoms of the fluoro monomers being partially replaced with photoactive groups of formula —Y—Ar—R in the copolymer; Y representing an oxygen atom or an NH group or a sulfur atom, Ar representing an aryl group, preferably a phenyl group, and R being a monodentate or bidentate group including from 1 to 30 carbon atoms. The fluoro monomers of formula (I) of the copolymer include vinylidene fluoride and trifluoroethylene. Also, a process for preparing this copolymer, a composition including this copolymer, and a film obtained from the copolymer.

摘要： The invention relates to a process for reducing the defectivity of a block copolymer (BCP1) film, the lower surface of which is in contact with a preneutralized surface (N) of a substrate (S) and the upper surface of which is covered by an upper surface neutralization layer (TC) in order to make it possible to obtain an orientation of the nanodomains of the block copolymer (BCP1) perpendicularly to the two lower and upper interfaces, where the upper surface neutralization layer (TC) employed to cover the upper surface of the block copolymer (BCP1) film comprises a second block copolymer (BCP2).
