題目： Block Co-polymers at Surfaces: Patterns, Templates and Electric Fields

要旨：Diblock copolymers exhibit a wide variety of spatially modulated phases
due to competing molecular and entropic forces. The resulting self-assembly nano-structures and morphologies have many uses and applications. In recent years an intensive effort has been devoted to control ordering of block copolymers close to surfaces and in thin film setups as is required by nano-lithography applications. In this talk I will review the basic properties of block copolymers and recent progress aimed at understanding the ways to control orientation of anisotropic block copolymer phases. In particular, I will explain how one can manipulate polymer films using patterned surfaces, molds (Nano Imprint Lithography) and electric fields to achieve the desired ordering and orientation of the film.
