摘要：
Electrochemical synthesis of polypyrrole (PPy) on copper electrodes is researched using different techniques. The synthesised films are found to be very adherent and homogeneous. The corrosion behaviour of Cu/PPy is assessed in a 3.5% NaC1 solution using polarisation curves and open circuit potential-time. The relationship between porosity and anticorrosive properties is demonstrated. The chronopotentiometry technique is seen to be the best to produce a good coating that yields good protection against copper corrosion for long immersion times. (c) 2007 Elsevier Ltd.
