Stable Oxide Nanoparticle Clusters Obtained by Complexation
J. -F. Berret, A. Sehgal, M. Morvan +3
We report on the electrostatic complexation between polyelectrolyte-neutral copolymers and oppositely charged 6 nm-crystalline nanoparticles. For two different dispersions of oxide…
Polymer-Nanoparticle Complexes : from Dilute Solution to Solid State
Jean-Francois Berret, Kazuhiko Yokota, Mikel Morvan +1
We report on the formation and the structural properties of supermicellar aggregates also called electrostatic complexes, made from mineral nanoparticles and polyelectrolyte-neutra…
Precipitation-Redispersion of Cerium Oxide Nanoparticles with Poly(Acrylic Acid) : Towards Stable Dispersions
A. Sehgal, Y. Lalatonne, J. -F. Berret +1
We exploit a precipitation-redispersion mechanism for complexation of short chain polyelectrolytes with cerium oxide nanoparticles to extend their stability ranges. As synthesized,…
Electrostatic Self-assembly : A New Route Towards Nanostructures
J. -F. Berret, P. Herve, M. Morvan +5
During the last 3 years, our group has investigated extensively the complexation mechanism between neutral-polyelectrolyte block copolymers with oppositely charged species. These s…
Interactions between Polymers and Nanoparticles : Formation of Supermicellar Hybrid Aggregates
J. -F. Berret, K. Yokota, M. Morvan
When polyelectrolyte-neutral block copolymers are mixed in solutions to oppositely charged species (e.g. surfactant micelles, macromolecules, proteins etc), there is the formation…
Stabilization and Controlled Association of Inorganic Nanoparticles using Block Copolymers
K. Yokota, M. Morvan, J. -F. Berret +1
We report on the structural properties of mixed aggregates made from rare-earth inorganic nanoparticles (radius 20 Angstroms) and polyelectrolyte-neutral block copolymers in aqueou…
