Nanostructured functional materials enabled by atom transfer radical polymerization Krzysztof Matyjaszewski Carnegie Mellon University, Center for Macromolecular Engineering, USA Many advanced nanostructured functional materials were recently designed and prepared by reversible deactivation radical polymerization. Copper-based ATRP (atom transfer radical polymerization) catalytic systems with polydentate nitrogen ligands are among the most efficient reversible deactivation radical polymerization systems. ATRP enables rational design of (co)polymers with specific architecture and functionality, followed by precise and efficient polymer synthesis and characterization to prepare advanced materials with target properties. Various copolymers, molecular brushes, hybrid materials, and bioconjugates were prepared with high precision. Examples of nanostructured multifunctional hybrid materials for applications related to biology, environment, and energy will be presented. 1-7 References 1.
