UV-Vis spectra show that the absorbance values at characteristic wavelengths of the multilayer films increase almost linearly with the number of chitosan/PTA bilayers, suggesting that the deposition process is regular and highly reproducible from layer to layer. XPS and FTIR spectra confirm the incorporation of chitosan and PTA into the films. AFM images indicate that the surface of the multilayer films is rough. The result of CV shows that the multiplayer films maintain good electrocatalytic activity of phosphotungstate acid.

UV-Vis结果显示多层膜在特征吸收峰处的吸光度数值随膜双层数增加逐渐增大，呈良好的线性关系，表明多层膜是均匀组装的；XPS和FTIR结果证实了壳聚糖和磷钨酸被组装到膜上，AFM图形显示膜表面有一定的粗糙度，CV结果说明多层膜保留了磷钨酸的电化学性质。
