Abstract:
Disclosed herein is a composition comprising a first block copolymer that comprises a first block and a second block; where the first block has a higher surface energy than the second block; a second block copolymer that comprises a first block and a second block; where the first block of the first block copolymer is chemically the same as or similar to the first block of the second block copolymer and the second block of the first block copolymer is chemically the same as or similar to the second block of the second block copolymer; where the weight percent based on total solids of the first block of the second block copolymer is greater than that of the first block of the first block copolymer; where the first block copolymer phase separates into a first morphology of cylindrical or lamellar domains when disposed singly on a substrate.
