Özet

Electropolymerization of m-aminophenol (MAP) on copper from aqueous phenylphosphonic acid (PPA) medium was achieved using cyclic voltammetry by applying three different scan rates namely 10mVs(-1), 50mVs(-1) and 100mVs(-1). Characterization of obtained poly(m-aminophenol) (PMAP) films were done by FTIR, SEM and AFM methods. FTIR data reveal the presence of C-O-C linkage in the polymer and suggest that monomer polymerized through -OH group. Corrosion performance of PMAP films was investigated in 0.1 M H(2)SO(4) using potentiodynamic polarization and EIS methods. Results show that corrosion performance of PMAP films depends on the scan rate used for electrodeposition. It was found that for short immersion periods PMAP films synthesized at 50mVs(-1) scan rate (PMAP(50)) to have the highest performance, PMAP films synthesized at 10mVs(-1) (PMAP(10)) to have moderate protection performance and that of PMAP films synthesized at 100mVs(-1) (PMAP(100)) to have least corrosion performance. However for long immersion periods the order of the performance was found to be as PMAP(100)>PMAP(10)>PMAP(50). (C) 2008 Elsevier B.V. All rights reserved.
