摘　　要：本研究使用电分析技术对比不同型号的商品化聚氨酯分散体的性质。通过测试聚氨酯膜电极的电流-时间曲线、交流阻抗谱和线性电位扫描曲线,分析不同聚氨酯膜在润湿速度、透水性和透氧率等方面的差异。本研究还分析和讨论了氯化钾对聚氨酯成膜过程、聚氨酯膜结构和性质的影响。本研究表明,在传感器开发中可以通过电分析技术对聚氨酯材料进行初步筛选,为聚氨酯膜配方设计提供支持,具有较高的实用价值。The present research compares properties of different commercial products of polyurethane dispersions by electroanalytical techniques. The differences on wetting rate, water and oxygen permeability are analyzed by current-time measurement, electrochemical impedance spectroscopy and linear sweep voltammetry. The present research further analyzes and discuss the addition of potassium chloride additive affect the polyurethane film formation, membrane structure and properties. The present research shows electroanalytical techniques can support the selection and modification of polyurethane film, providing practical value for sensor development.
