Macromolecular Materials Chemistry Lab (MMCL) pursues to establish synthetic pathways to macromolecules with complex shape and structure, and thus develop advanced polymeric nanomaterials for energy and environmental applications. We are particularly interested in controlling polymer structure, conformation and phase separation in a spatiotemporal manner. Current topics include architectured polymer syntheses, postpolymerization modification, polymerization-induced nanostructuring, and porous materials.
We synthesize polymers. We utilize controlled polymerization techniques to produce well-defined polymers. We combine different polymer chains and build up complex architectures, so the resulting nanostructured polymers can exhibit desired functions and properties that cannot be realized with simple polymer materials. We also take synthetic challenges and develop methodologies for polymer synthesis, by postpolymerization modification for instance.
Controlled polymer synthesis Architecture control Compartmentalization Postpolymerization modification
We design nanostructure of our polymers when we synthesize them. In particular, we strongly exploit block polymer self-assembly that takes place in situ during polymerization. This synthetically feasible and scalable approach allows us to produce interesting nanomaterials with control morphology and length scale of the nanostructures. Synthesis of nanoporous materials and their applications for energy and environmental applications are actively sought.
