Abstract

The pursuit of engineering macroscopic properties in polymeric materials has heightened the need to precisely control polymer microstructure, including architecture, size, and chemistry. Advances in synthetic methodologies and characterization techniques have facilitated the creation of well-defined functional polymers, establishing efficient structure-function relationships. However, challenges persist in independently controlling design parameters to elucidate molecular relationships between microstructure and macroscopic properties. To address this limitation, my research focused on developing synthetic methodologies for tuning the architecture, size, and composition of densely grafted polymers, known as bottlebrush polymers. This thesis outlines several methodologies for enhancing chemical tunability through side chain chemistry, bottlebrush polymer size, and architecture. These methods enable precise control over the shape (e.g., varying brush lengths along the backbone), chemistry (e.g., diverse brush chemistries and end-group functionalities), and size (e.g., brush and backbone lengths) of bottlebrush polymers, accompanied by rigorous characterization. The methodologies detailed in this thesis enhance the chemical tunability of bottlebrush polymers, providing a unique platform for correlating polymer microstructure with macroscopic properties. This approach aims to establish effective design rules and structure-function relationships for targeted applications in polymeric materials.
