End-on Chain orientation of Poly(3-alkyl thiophene)s on a substrate via Microphase Separation of Amphiphilic Diblock Copolymer |
| 초록 |
To fabricate end-on orientation of Poly(3-alkyl thiophene) (P3AT) where the polymer main chains are vertically oriented on the substrate, amphiphilic diblock copolymers consisting of P3ATs were synthesized. We investigated phase behavior of poly(3-dodecyl thiophene)-block-poly(3-(2-(2-(2-methoxyethoxy)ethoxy)ethoxy)methylthiophene) (P3DDT-b-P3TEGT) with various weight fractions of P3DDT block (wP3DDT). P3DDT-b-P3TEGTs were spin-coated on the substrate and thermally annealed to construct lamellar structure. P3DDT-b-P3TEGT showed parallel oriented lamellar structure to the substrate that P3TEGT is located at substrate/polymer interface and P3DDT is located at polymer/air interface. Because the P3AT chains are oriented in a perpendicular direction to the direction of the lamellar microdomain, polymer chains form a vertical orientation on the substrate. P3DDT-b-P3TEGT showed improved mobility than that of P3DDT, indicating that end-on orientation is effective in improving conductivity. |
