TITRE : STRAPA (Multi STimuli Responsive Aqueous Polymer Assemblies)
Projet scientifique:
The development and application of multi-stimuli responsive materials is a burgeoning field of study in
leading research groups in the USA, Asia and mainland Europe (at present this field is underrepresented
in France). Such soft advanced materials are expected to revolutionize nano-science, engineering and
technology and, therefore, they are key to many countries future technological competitiveness.
However, there is no doubt that the creation of such high performance materials relies directly on our
ability to manipulate these “smart” materials in a controllable, predictable and orchestrated fashion at
the molecular and also at supramolecular level.
In this context, during this training course, we propose to engineer and study a new class of
supramolecular polymer materials including block copolymers, branched polymers, star (co)polymers,
and networks structures capable of responding to multiple external stimuli in a controllable and
predictable fashion in aqueous environments. The architectures of these materials will be constructed by
specifically bringing together complementary well-defined polymer building blocks (prepared by
Controlled Radical Polymerization) with specially designed host/guest motifs attached in specific
locations on polymer backbones. Then, we will exploit well-defined polymer building blocks whereby
the “periphery” can be reversibly modified. This lock and key approach will offer the unique
opportunity to control polymer structure (e.g topology and morphology) and properties. Furthermore,
the inherent reversibility of supramolecular architectures will allow “on demand” modular and tunable
modification of structure and properties of appropriately functionalized macromolecules, and thus will
afford novel systems with applications in materials science and nanotechnology.
