Abstract
Disclosed herein is a method comprising disposing a first composition comprising a first block copolymer upon a substrate; where the first block copolymer comprises 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 disposing a second composition comprising an second copolymer upon a free surface of the first block copolymer; where the second copolymer comprises a surface free energy reducing moiety; where the surface free energy reducing moiety has a lower surface free energy than the first surface free energy and the second surface free energy; the second copolymer further comprising one or more moieties having an affinity to the first block copolymer; where the surface free energy reducing moiety is chemically different from the first segment and from the second segment.
