- 摘要:
- 通过循环伏安法在不锈钢基体上制备聚苯胺(PANI)膜，探讨了合成条件对聚苯胺性能的影响，并采用开路电位和动电位极化曲线等方法研究了聚苯胺膜对不锈钢的腐蚀防护性能。结果表明，在硫酸浓度为0.65 mol/L，苯胺浓度为0.1 mol/L和扫描周期为15的条件下，可以获得性能较好的聚苯胺膜。制备的聚苯胺膜为掺杂态，其对苯胺的电化学聚合具有催化作用。聚苯胺膜的存在起到一定的钝化作用，对不锈钢有较好的腐蚀防护性能。
- Abstract:
- Polyaniline(PANI) film was synthesized on stainless steel by cyclic voltammetry polymerization, the synthesis conditions on the influence of polyaniline performance were discussed, and the corrosion protective properties of polyaniline film were researched by means of open circuit potential (OCP) and potentiodynamic polarization technique. The results showed that the polyaniline film with high conductivity and good compactness could be obtained with the H2SO4 concentration of 0.65 mol/L, aniline concentration of 0.1 mol/L and the scanning cycles of 15. The prepared polyaniline was doped, and could catalyze the electrochemical polymerization of aniline. The existence of the polyaniline film played a certain role passivation that had good corrosion protection to stainless steel.
