Abstract:
Highly charged molecules and nano-assemblies serve as unique building blocks in nanochemistry because they are involved not only in electrostatic but also in specific non-covalent interactions. Nano-sized 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. Depending of the precursors, polymer/nano-ion interaction can lead to formation of nanoparticles, gels or nano-structured materials suitable for drug delivery of ion-battery applications.
