The combination of polyaniline (PANI), a conductive polymer, and a corrosion inhibitor has been studied to manufacture anti-corrosion coatings. This paper introduces some research results on PANI-DPA, a new material combining polyaniline with decylphosphonic acid, an environmentally friendly corrosion inhibitor, synthesised via two emulsion methods: in direct and inverse emulsions. The polymerisation was performed at room temperature by using ammonium peroxydisulfate (APS) as oxidant and decylphosphonic acid (DPA) as surfactant. The diff erences in the properties of synthesised PANI-DPA from the two methods were studied in detail. The structure of nano-bars (100-200nm) and nanofibres (50-100nm) were observed in the inverse emulsion and direct emulsion system, respectively.
