Bottlebrush copolymers has received a considerable attention recently because of their unique characteristics. While most of recent work has focused on the bottlebrush copolymers comprising symmetric length of side chains, only a few studies have been reported on the bottlebrush copolymer with asymmetric length of side chains. To expand the potential applications, a systematic synthesis of bottlebrush copolymers and overall investigation on their morphologies are required. In this work, we synthesized a series of well-defined brush random copolymers where short PS and long PLA side chains are statistically grafted to a polynorbornene backbone. By adjusting the feed ratio of PS and PLA macromonomers, brush random copolymers having a variety of composition were prepared. The selective removal of PLA from these brush random copolymers produced nanoporous structures with tailored porosity and pore sizes, which was largely dictated by the initial composition of brush random copolymers. |
