Rapid synthesis of polyethylenimine-protected Prussian blue nanocubes through a thermal process

Polyethylenimine (PEI)-protected Prussian blue nanocubes have been simply synthesized by heating an acidic mixture of PEI, FeCl3, K3Fe(CN)(6), and KCI. The experiment results presented here demonstrate that the pH of the mixture plays an important role in controlling the shape and composition of the resultant product.
