文摘

Block copolymer inverse micelles from polystyrene-block-poly-2-vinylpyridine (PS-b-P2VP) deposited as monolayerfilms onto surfaces show responsive behavior and are reversibly switchable between two states of different topographyand surface chemistry. The as-coated films are in the form of arrays of nanoscale bumps, which can be transformedinto arrays of nanoscale holes by switching through exposure to methanol. The use of these micellar films to act asswitchable etch masks for the structuring of the underlying material to form either pillars or holes depending on theswitching state is demonstrated.
