Abstract: Polyaniline films were deposited on marine grade 5083 aluminium, and were examined and characterised with the use of cyclic voltammetry, UV-Vis spectroscopy and SEM imaging. The polyaniline films were electrochemically synthesised from 0.5 M oxalic acid solutions containing 0.1 M aniline, under potentiostatic control. The presence of polyaniline was clearly seen by the presence of two sets of redox peaks in the voltammograms, and by two absorptions in the UV-visible spectrum. The successful application of polyaniline films with antimicrobial properties can potentially lead to future applications of antifouling coatings for use in the marine environment.

Keywords: polyaniline films; electrochemistry; antifouling coatings; electrochemical synthesis; marine grade aluminium; marine environment; antimicrobial properties; nanotechnology.
