| Outline of Final Research Achievements |
In this study, nano-/micro-patterns formed by AB type block copolymers (BCP) including a mesogen-like moiety between the blocks have been investigated. The BCPs contains three different hydrophobic blocks: poly(L-lactide), poly(caprolactone), and poly(trimethylene carbonate).
As a consequence of AFM analysis of spin-coated samples, each BCP exhibited anisotropic structure by annealing after the spin-coating. When two different BCPs were mixed and spun (AB + AB’), introduction of a different hydrophobic block as the third component enhanced the phase separation to induce anisotropic structure. In addition, inorganic salts were found to contribute to construction of different types of larger structure of anisotropic aggregates formed in water, which structure (pattern) depends on the type of BCPs.
