中文摘要: |
采用循环伏安法合成了一种新的聚合物膜— — —聚 8-羟基喹啉膜,推测了聚合的机理,通过红外光谱分析了聚合膜的组成。 采用单因素实验优化了成膜条件,结果表明,循环伏安法形成聚 8-羟基喹啉膜的最佳条件是:8-羟基喹啉浓度为 0 . 002 mol / L,氢氧化钠浓度为 0 . 4 mol / L,扫描速度 30 mV / s,扫描 8 圈。 采用该成膜条件在镀镍工件上电沉积聚 8-羟基喹啉,其表面形成了一层浅黄色明亮光滑的致密薄膜,达到封孔目的,使得工件的耐蚀性显著提高。 |
英文摘要: |
The poly-8-hydroxyquinoline was firstly prepared by cyclic voltammetry. The mechanism of polymerization was speculated, and the composition of the polymer film was studied with infrared spectros-copy. Tafel testing was used in order to optimize the treatment for electrodeposition. The result shows that: the best condition of cyclic voltammetry method to synthesize corrosion-resistance polymer film is: the concentration of 8-hydroxyquinoline is 0 . 002 mol / L, sodium hydroxide is 0 . 4 mol / L, the scan rate is 30 mV / s, and scan 8 laps. A bright and smooth yellow film is obtained and the corrosion-resistance performance of the nickel plating work piece processes under the optimized condition was improved significantly. |
