COPOLYMER FORMULATION FOR DIRECTED SELF-ASSEMBLY, METHODS OF MANUFACTURE THEREOF AND ARTICLES COMPRISING THE SAME

摘要

Disclosed herein is a composition comprising a block copolymer; where the block copolymer comprises a first polymer and a second polymer; where the first polymer and the second polymer of the block copolymer are different from each other and the block copolymer forms a phase separated structure; an additive polymer; where the additive polymer comprises a bottle brush polymer; where the bottle brush polymer comprises a homopolymer that is the chemically and structurally the same as one of the polymers in the block copolymer or where the additive polymer comprises a graft copolymer that has a preferential interaction with one of the blocks of the block copolymers; and a solvent.

1. A composition comprising:
a block copolymer; where the block copolymer comprises a first polymer and a second polymer; where the first polymer and the second polymer of the block copolymer are different from each other and the block copolymer forms a phase separated structure when independently disposed on a substrate, and where the first polymer and the second polymer have a difference in surface energy of larger than 0.5 mN/m; an additive polymer; where the additive polymer comprises a bottle brush polymer; where the bottle brush polymer comprises a homopolymer that is the chemically and structurally the same as one of the polymers in the block copolymer or where the additive polymer comprises a graft copolymer that has a preferential interaction with one of the blocks of the block copolymers; and a solvent.
