Microphase-separated nanostructures in block copolymers have fascinated one to understand the correlation between their ordered structures and the polymer structures so far, and now a new wave is surging on them as the self-assembled nanostructures leading to industrial use as the coming engineered plastics. Emphasis should be placed on both high reproducibility and mass production of these ordered nanostructures through self-assembling nanofabrication processes, expected as one of the powerful counterparts of the top-down-type nanofabrication such as lithography and beam processing. Recently, we have developed a series of PEO – liquid crystalline (LC) block copolymers which consist of poly(ethylene oxide) (PEO) and polymethacrylate bearing azobenzene mesogen in the side chain and have fabricated hexagonally arranged and normally aligned PEO nanocylinder domain structures in their thin films on a roll-type PET film substrate which were prepared by continuous coating with a microgravure. This success satisfies the above requirements applicable to industrial use and also guarantees their high regularity as reliable nanotemplates for structural transcription to and hybridization with various materials such as metal, semiconductors, and so on. In this talk, our recent successful coating and several topics on transcription and hybridization will be introduced, together with our polymer designs such as photocrosslinkable nanostructured films. |
