Formation of Vertically Oriented Nanostructure in P3DDT-b-PLLA Thin Film via Solvo-Microwave Annealing |
| 초록 |
Conjugated polymer-based block copolymers (BCPs) have attracted a great attention for their potential in manufacturing nanoscale organic conducting pathways. Herein, fabrication strategies of well-defined organic conducting pathway using BCP self-assembly are demonstrated. A series of poly(3-dodecylthiophene)-block-poly(l-lactic acid) [P3DDT-b-PLLA] that contains conjugated block and removable coil block were synthesized. Afterward, we successfully assembled P3DDT-b-PLLA into well-ordered lamellar and cylinders with vertically orientation relative to the silicon substrate using a solvo-microwave annealing technique. Such perpendicular orientation of BCP was achieved by appropriate selection of the annealing solvent that can generate neutral interfacial interaction at BCP / air. Further selective removal of PLLA block in thin films using sodium hydroxide (NaOH) solution, followed by a DI-water/MeOH co-solvent washing resulted in well-defined organic conducting pathway. |
