摘要:

采用化学氧化聚合法合成了一系列十二烷基苯磺酸掺杂的聚吡咯(PPy-DBSA), 并研究了其电化学防污性能. 循环伏安(CV)曲线表明, PPy-DBSA在天然海水中具有良好的电化学活性和稳定性. 采用循环伏安扫描方法实现阳极极化和阴极极化交替进行, 并对极化后的PPy-DBSA电极进行了抑菌性能研究, 发现PPy-DBSA在循环伏安阳极-阴极交替(-1.0~2.0 V vs. SCE)极化下, 可成功抑制微生物(大肠杆菌)的附着, 其中在-0.6~0.8 V范围内循环伏安阳极-阴极交替极化20 min时防污效果最佳, 抑菌率可达99.8%, 明显优于恒电位阳极极化和恒电位阴极极化的结果.

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.
