Design and Synthesis of Supramolecular Structures for the Controlled Release of Sulfur Signaling Species
… efforts to investigate fundamental micelle–unimer relationships. This section includes an evaluation of the impact of core-forming block mobility on micelle–unimer coexistence utilizing a model polymer amphiphile system. Unimer populations correlated with glass transition temperatures of the …

Effect of Encapsulated Species on Block Copolymer Micelle Self-Assembly
… number and size, and dynamic processes, such as unimer exchange, were investigated. In the first study, micelles containing poly(ethylene oxide)-b-polycaprolactone [PEO-PCL] diblock copolymers in water/THF mixtures were investigated. The presence of THF altered the interfacial tension between the …

Block Copolymer Solutions: Transport and Dynamics, Targeted Cargo Delivery, and Molecular Partitioning and Exchange
… coefficients and populations of micelles and unimers (i.e. free polymer chains in solution) over a range of temperature (21 – 50 °C) and solvent composition (10 – 100 vol % THF-d8). By mapping the micelle-unimer coexistence phase diagrams, we are able to enhance our ability to understand and …

Multiscale Transport and Dynamics in Ion-Dense Organic Electrolytes and Copolymer Micelles
… and diffusion results that inform on the unimer exchange mechanism. These convenient NMR methods thus offer an economical alternative (or complement) to time-resolved small angle neutron scattering (TR-SANS).

Novel amphiphilic diblock copolymers by RAFT-polymerization, their self-organization and surfactant properties
… temperature of the core-forming block, unimer exchange occurs between the micelles. Despite the dynamic character of the polymeric micellar systems, the aggregation behavior is strongly dependent on the history of the sample, i.e., on the preparation conditions. The aqueous micelles …
