【摘要】：聚合物太阳能电池材料表面柔软、粘弹性较强,很容易粘滞探针,从而影响到原子力显微镜的成像质量。本文通过比较轻敲模式、智能成像以及快速扫描模式三种原子力显微镜成像模式对聚合物太阳能电池材料的形貌和相位成像情况,分析探讨了探针型号的选择、作用力控制、扫描速率等参数对成像清晰度和准确性的影响。通过比较可知,弹性系数较小及具有反射镀层的探针均有利于聚合物类样品的检测;控制探针与样品之间较小作用力也有利于获得丰富的形貌信息;另外,扫描速率太高不利于获得细节形貌信息,应将扫描速率控制在一定范围内。因此,选择合适的成像条件和设置适当的扫描参数对原子力显微镜成功应用于分析表征聚合物太阳能电池材料样品具有十分重要的意义。
[Abstract]:The polymer solar cell material has soft surface and strong viscoelasticity, which makes it easy to stick the probe, thus affecting the imaging quality of atomic force microscope (AFM). In this paper, by comparing the morphology and phase imaging of polymer solar cell materials with three AFM imaging modes, such as tapping mode, intelligent imaging mode and fast scanning mode, the selection of probe type and force control are analyzed and discussed. The effect of scanning rate and other parameters on imaging clarity and accuracy. By comparison, it can be seen that the small elastic coefficient and the probe with reflective coating are beneficial to the detection of polymer samples, the control of the small force between the probe and the sample is also conducive to obtaining abundant morphology information. The scanning rate is too high to obtain the detailed morphology information, so the scanning rate should be controlled within a certain range. Therefore, selecting appropriate imaging conditions and setting appropriate scanning parameters are of great significance for the successful application of AFM in the analysis and characterization of polymer solar cell materials.
