Abstract:
Disclosed herein is a block copolymer comprising a first segment and a second segment that are covalently bonded to each other and that are chemically different from each other; where the first segment has a first surface free energy and where the second segment has a second surface free energy; and an additive copolymer; where the additive copolymer comprises a surface free energy reducing moiety where the surface free energy reducing moiety has a lower surface free energy than that of the first segment and the second segment; the additive copolymer further comprising one or more moieties having an affinity to the block copolymer; where the surface free energy reducing moiety is chemically different from the first segment and from the second segment; where the additive copolymer is not water miscible; and where the additive copolymer is not covalently bonded with the block copolymer.
