摘要: Abstract A polystyrene- block -poly(4-vinyl pyridine) diblock copolymer (PS- b -P4VP) has been used to create nanosized toroid-like structures on nitrided silicon oxide and gold substrates via simple solvent annealing of spun cast films. The significance the role polymer–substrate interactions in defining morphology self-assembled structure is discussed.
