Block copolymers (BCPs) can provide an easy yet efficient way to fabricate well-ordered structures via their self-assembly property AB diblock copolymers are exhibiting the self-assembled structure 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. Also, another structure can be obtained by blending ABC triblock copolymer and diblock copolymers. To investigate the structural difference between the diblock copolymer, triblock copolymer and blending, the spin-coated thin films were phase-separated by solvent annealing by using AFM. To distinguish the structure of triblock copolymers, silver and gold were selectively attached to specific domains by using TEM. In this study, it was shown that the structure of triblock copolymer can be controlled by various factors suggesting the potentials of triblock copolymers in various applications. |
