1 and 2D Mineral Polyelectrolyte: Synthesis, Structure, Properties and Applications

In this presentation I will present the very rich zoology that has been brought to light in the field of mineral/inorganic polyelectrolyte, whether they are (i) unidimensional with the highly flexible polyelectrolyte KPdPS₄ and its self assembly (Sayetat et al, Angew. Chem.), NaNb₂PS₁₀ which self assemble to form nanotube structures (Camerel et al. Nanoletters), Li₂Mo₆Se₆ which forms a nematic mesophase (Gabriel et al. Adv. Mater.) or (ii) bidimensional with the demonstration of the nematic structure of smectic clays nanosheet suspensions (Gabriel et al J. Phys. Chem.) or even the discovery of the first lamellar phase based on covalent nanosheets in H₃Sb₃P₂O₁₄ (Gabriel et al. Nature & PNAS). This latter phase, presenting an exceptional hyperswelling behavior, so large that it enable light diffraction (unpublished results).

Such a variety of behaviors make of these polyelectrolyte solutions some very interesting models for the development of new theoretical approaches as well as potential applications.
