제목 Control of Lateral Ordering and Vertical Orientation in Amphiphilic Block Copolymer Thin Films and Their Applications for Nano-reactors
초록 It has been shown that PS-b-PEO block copolymer thin films exhibit the good lateral ordering with the vertically oriented microdomains via solvent annealing. In this case, the relative humidity plays a crucial role to control the ordering and vertical orientation of microdomains. This implies that the interaction between the water and the hydrophilic block induces such morphologies. In this work, we expand and generalize this idea to the other hydrophilic blocks such as PDMA-b-PS block copolymers. At low humidity conditions, the cylindrical PDMA domains were oriented parallel to the substrate, while the vertical orientation with the good lateral ordering was achieved at high humidity conditions. Furthermore, the facile synthesis of such system via CLRP can be used to design many useful block copolymer templates. For example, a ternary amine group in the PDMA domain can be effectively used to stabilize the various metallic compounds such as Au or Pt, acting as nano-reactors.
