Abstract:

Dodecyl benzene sulfonic acid doped polypyrrole(PPy-DBSA) samples were synthesized by oxidative chemical polymerization, and their electrochemical antifouling performances were studied. Cyclic voltammetry(CV) curve showed that PPy-DBSA had excellent electrochemical activity and stability in natural seawater. The antimicrobial activity of PPy-DBSA under alternating anodic-cathodic polarization was verified by CV curve. It was found that the adhesion of microorganisms(E. coli) to PPy-DBSA electrode was efficiently inhibited by cyclic voltammetry scanning(-1.0—2.0 V vs. SCE) under alternating anodic-cathodic polarization. The inhibition rate could reach 99.8% after alternating anodic-cathodic polarization between -0.6 V and 0.8 V for 20 min, which is superior to that under pure anodic polarization and pure cathodic polarization.
