Abstract
A carbazole-based graft copolymer capable of controlling a self-assembled structure and a method of synthesizing the same are provided. Specifically, the copolymer is capable of controlling a self-assembled structure which can control the morphology of a polymer structure and the size of pores by controlling the molecular weights of polylactic acid (PLA) functioning as a coil and of a carbazole copolymer to prepare a poly(carbazole)-coil graft copolymer of Formula 1 below and the method of synthesizing the same is provided. In Formula 1, X represents 0.05 to 0.1, m represents an integer of 7 to 8, and n represents an integer of 56 to 84.
