Outline of Final Research Achievements

Feasible nanopatterning in polymer blends was first achieved by our group via epitaxial crystallization of crystalline polymer onto crystallizable solvent. In this study, this method is applied to blends of conducting polymers in an effort to develop ideal nanostructure for organic semiconductor devices. Creation of nano-scale lamellar patterns has been succeeded in polymer blends containing regioregular poly(3-hexylthoiphene). Further, through the application of the method to various polymer blends, mechanism that allows the formation of highly oriented lamellar patterns in nano-scale has been revealed.
