Contexte

Block copolymers are fundamental building blocks in material science, widely used for their ability to self-assemble into periodic nanostructures (spheres, cylinders, lamellae). However, synthesizing these architectures requires complex and costly living polymerization techniques. We aim to explore an alternative using dynamic covalent chemistry. By introducing exchangeable bonds into linear and branched polymers, we aim to allow the material to « find » its own optimal topology, effectively self-synthesizing ordered block-like structures from random precursors driven by thermodynamic forces.
As a Postdoctoral Researcher, you will study the self-assembly in solution of these dynamic covalent polymers. Your goal is to correlate the chemical dynamics of the exchangeable bonds with the physical self-assembly of the polymer chains. You will investigate how these dynamic polymers organize in selective solvents (micellization) and how they can be processed into nanostructured materials for energy-relevant applications.
