Block copolymers can provide an easy yet efficient way to fabricate well-ordered structures via their self-assembling behavior. AB diblock copolymers exhibit the self-assembled nanostructures such as spheres, cylinders, gyroids, or lamellae. The self-assembled structure of the ABC triblock copolymer is more complex and diverse than AB diblock copolymer due to increased number of variables. In our work, another structure was pursued by blending ABC triblock copolymer with diblock copolymers. ABC triblock copolymers and their blends were spin-coated on the substrate to generate the films, and then annealed under solvent vapor. Their structure was investigated by AFM, SEM and TEM. To distinguish the structure of block copolymers, iodine and gold were selectively attached to specific domains. In this study, the structure of triblock copolymer which could not be seen in AB diblock copolymer, was observed and analyzed thoroughly, compared to the cases of AB diblock copolymers and the blends. |
