A simple method is reported in this work for the preparation of charge-stabilized Prussian Blue nanocrystals of readily adjustable size. They have been purified by addition of non-solvents and redispersed in water without aggregation. PB nanocrystals have been electrostatically arranged along single polycation chains adsorbed onto flat surfaces or along carbon nanotubes precoated by a polycation. In the latter case, carbon nanotube-polyelectrolyte-Prussian Blue hybrids are formed, that might be useful materials for the manufacture of electrooptical devices or mechanically robust ion-sieving membranes.
