【摘要】：采用具有600 nm周期的一维硅光栅来表示等高粗糙表面,研究AFM的测试参数对等高粗糙表面的黏着影响。实验所使用的探针为平头探针(PL2-CONTR-10,Nanosensors),其针尖直径为2μm,实验分别在空气中以及干燥环境下进行,通过力曲线的测量,计算出黏着力的平均值以及标准差。结果表明:载荷与停留时间会引起黏着力的略微增大或减小,但总体影响不是很大;在空气中,随着退针速率加快,黏着力先表现出先增大然后减小的趋势;而在干燥环境下,黏着力随着退针速率的加快逐渐减小。
[Abstract]:A one-dimensional silicon grating with a period of 600 nm is used to represent the equi-high rough surface. The influence of AFM parameters on the adhesion of rough surface was studied. The probe used in the experiment was PL2-CONTR-10 Nanosensors. The diameter of the tip was 2 渭 m. The experiment was carried out in air and dry environment, and the force curve was measured. The average value and standard deviation of the adhesion force are calculated. The results show that the load and residence time will cause a slight increase or decrease of the adhesion force, but the overall effect is not very great. In the air, the adhesive force increases first and then decreases with the increase of the speed of needle withdrawal. In the dry environment, the adhesive force decreases with the increase of the speed of needle withdrawal.
