제목 Study of hierarchical nanostructures of patterned block copolymer films and its dewetting phenomena during solvent annealing
초록 The treatment of block copolymer thin film with its solvent vapor has been known as an effective way to control both orientation of microdomains with respect to the substrate and their registration into a well defined periodic lattice structure. Poly(styrene-b-ethylene oxide) has been utilized to demonstrate a microdomain structure ordered perpendicular to the surface which is applicable for an organic nanostructured membrane. In order to fabricate a patterned block copolymer film with a few microns in size for the confined dewetting, we have recently developed a new technique called Transfer Printing where a polymer thin film spin cast directly on a patterned PDMS mold. Subsequent solvent vapor treatment of transferred film induces dynamic dewetting behavior and hierarchical ordering of nanostructures. The controlled structures were characterized by Optical Microscope, Atomic Force Microscope.
