【摘要】 利用微接触印刷的方法制备了图形化的自组装膜。考察了膜的表面性质对接触式原子力显微镜(AFM),摩擦力显微镜(FFM)和剪切力显微镜(SFM)的成像的影响。发现 AFM 能反映样品的表面形貌,而 FFM 和 SFM 的成像受表面性质的影响较大,在表面性质差别很大的图形表面上会出现图像衬度与表面形貌反转的现象。更多还原

【Abstract】 Chemically distinct patterned surfaces have been fabricated through microcontact printing technique. Contact mode atomic force microscope(AFM),friction force microscope(FFM),and shear force microscope (SFM)were used to map the patterns.AFM images were correlated well with the surface topography. However,FFM and SFM contrast were inverted with respect to the topography,indicating the strong influence of surface property on FFM and SFM imaging.The mechanism of the contrast inversion has been discussed.更多还原
