Block copolymers enable the design of well-defined supramolecular structures for engineering and biological applications. Controlled radical polymerization (CRP) techniques enabled the synthesis of well-defined macromolecules with molecular weight control and narrow polydispersity (PDI). Reversible addition-fragmentation chain transfer (RAFT) polymerization is currently one of the most versatile CRP techniques to afford complex macromolecules with highly controlled architecture leading to block copolymers with tailorable properties. The introduction of electrostatic interactions as well as hydrogen bonding enhances the microphase separation in chain-growth polymers. Control over block composition enables tailored charge content, tunable thermomechanical properties, and nanoscale morphology. This presentation will describe efforts with different classes of tailored copolymers that impart a specific functionality tailored mechanical, rheological, and ion-transport properties. These copolymer architectures represent various synthetic approaches towards designing functional macromolecules for broad range of applications with a focus on electro-active membranes and switchable adhesives.
