WebJun 16, 2024 · This indicates that the SSM/PPY(AOT) membrane performs better in antifouling in the M RO mode. However, as shown in Figure 5D,E, the signals associated with Ca and Mg in the XPS spectra for the fouled membrane surface (M RO) significantly increased, suggesting complexation between Ca 2+ /Mg 2+ and sulfonic acid groups on … WebThe thicker PPy/DDS films were found to be significantly rougher than the thinner ones. Concerning porosity, whereas the 0.04 μm thick film possesses a predominantly microporous structure (≈57% of total porosity), the thicker films (0.2 μm and 1 μm) are mainly mesoporous (≈75%), or in the case of 5 μm thick film, almost entirely (≈98%) … WebApr 10, 2024 · 电化学阻抗谱介绍. 交流 阻抗 法 (alternating current impedance, AC impedance)是指控制通过电化学系统的电流 (或电势)为小幅度正弦交流信号，同时测量相应的系统电势 (或电流)随时间的变化，或者直接测量系统的交流阻抗 (或导纳)，进而分析电化学系统的反应机理 ... hide from people
