| 摘 要： | 研究了添加不同颜基比(P/B)ZnO的聚氨酯涂料在3.5%氯化钠溶液中的电化学阻抗谱特征, 结果表明, 添加量为P/B=1的涂层, 颜料分布均匀适中, 具有最佳抗介质渗透性能, 耐盐雾性能较好, 且该涂层特征频率较低, 表明其具有最小的涂层缺陷面积。

| Abstract: | The anti-diffusion of ZnO/polyurethane coatings were studied by using the impedance spectroscopy technique. Results indicate that the coating with P/B=1 has the best anti-diffusion and salt spray performance, the breakpoint frequency of the coating with P/B=1 is lower than others, which indicates the smaller defect area. |
