Vertically Oriented Nanostructures of Poly(3-dodecylthiophene)-Containing Rod-Coil Block Copolymers |
| 초록 |
We synthesized star-shaped 18-arm Polystyrene-block-poly(3-dodecylthiophene) copolymers having lamellar microdomains, based on the cyclodextrin core. Because of chain architecture of star shaped block copolymer, thin film of star shaped PS-b-P3DDT showed vertically oriented lamellar microdomains on a silicon substrate without any surface modification. On the other hand, the corresponding linear PS-b-P3DDT diblock copolymer thin films showed parallel oriented lamellar nanopattern with fibrils at surface. Moreover, the crystalline of P3DDT block in star shaped PS-b-P3DDT on substrate was well maintained after phase separation. |
