    This work presents the electrophoretic (EPD) of TEMPO-oxidised nano-fibrillated cellulose (TEMPO-NFC) coatings. Mechanism of anodic deposition of TEMPO-NFCs was analysed based on the results of atomic force microscopy (AFM), ellipsometry and quartz crystal microbalance (QCM). The ability of the EPD technique to deposit films from relative dilute solutions (0.01%) was demonstrated. Additionally, the structures produced by EPD were compared to those produced by dip and spinning coating methods to determine differences in nanotopographic surface roughness and hydrophilicity. Overall, NFC-TEMPO coatings produced using the EPD method offer a potential starting point for the next generation of biobased coatings.
