ABSTRACT:
A system for preparing oriented block copolymer structures includes a copolymer solution, a device capable of providing a flow field and an evaporation device. The device can be at least two cylinders that are parallel and adjacent to one another to form a nip and a driving mechanism to rotate each cylinder. Means for controlling a solvent environment and evaporation are provided. A method for preparing oriented block copolymer structures includes providing at least two cylinders which are parallel and adjacent to one another so as to form at least one nip, rotating each of the cylinders such that at the nip the cylinder surfaces are moving in the same direction with substantially the same or different tangential velocity, introducing a block copolymer solution into one of the nips of the rotating cylinders, thereby subjecting the polymer solution to a flow field and whereby orientation of the solution begins and evaporating the solvent from the block copolymer solution, whereby ordered microphase separation occurs and the oriented block copolymer structure is formed on the surface of at least one cylinder.
