PhD fellow in Hybrid Nanostructures Based on Polymer-Ions Interaction
Project supervisor: Pavel Matějíček
Highly charged molecules and nano-assemblies serve as unique building blocks in nanochemistry. Bulky and multivalent ions are known to readily condense on polyelectrolyte chains or brushes. Such ions are therefore capable to co-assemble with double-hydrophilic block copolymers into core/shell nanoparticles. It brings new function into the system and also introduces sensitivity to external stimuli, both depending on the nature of the charged specie. Besides co-assembling with polymers, a structure of hydration shell and a propensity of ions to specific interactions are interesting per se. It can lead to a complex solution behavior and the corresponding formation of nano-aggregates.
Skills in nanochemistry and synthetic chemistry are welcomed!
