The 3D topography of fractured surfaces was reconstructed and quantified by the means of SEM stereo pairs, image processing and analysis, and computer vision. It was shown that measured 3D roughness indexes Rs, Rq and Rmax have good positive relations to the crack propagation part of absorbed impact energy. Although fractal behavior had been checked out on the fractured surfaces, the fractal dimension was found nonsensitive to the fracture mode and mechanical properties. The geometric characteristics of fractal fractured surfaces should be quantified in fractal dimension together with absolute parameters.

In short,the improvement of surface hydrophilicity is attributed to both the formation of polar oxygenous group and the increase of surface roughness.

可见，聚丙烯表面亲水性的提高来源于含氧基团数量的增加和表面粗糙度的增加。

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。
