Poly(amidehydroxyurethane) template magnetite nanoparticles electrosynthesis: I. Electrochemical aspects and identification

A new method for the electrochemical synthesis and surface-functionalization of magnetite nanoparticles (NPs) with poly(amidehydroxyurethane) (PAmHU) is presented. Transmission Electron Microscopy shows the formation of NPs PAmHU cluster systems with individual NPs ranging in size from 6 to 42 nm. Electron Spectroscopy for Chemical Analysis, Electron Paramagnetic Resonance measurements, and X-ray Diffraction show that the electrochemically synthesized product contains NPs formed by a core-coating polymer system with an inner-core consisting of magnetite entities with crystallites dimensions within 6 to 11 nm. The resulting functionalized NPs are water-soluble and stable for months.
