摩擦强度对薄膜表面形态的作用:原子力显微镜下的观察

摘要

The effect of the rubbing strength on the surface morphology of rubbed polyimide films is demonstrated. Atomic force microscopy images show that mechanical rubbing produces microgrooves with rich subtle surface features on the surface of the polyimide films, and reveal that the surface topography of the polymer film is modified by the mechanical rubbing.%展示了摩擦强度对聚酰亚胺薄膜表面形态的影响.原子力显微图像显示,机械摩擦会使聚酰亚胺薄膜表面上形成微沟槽.这些沟槽的表面具有丰富的表面精细构造.原子显微图像还揭示了机械摩擦可以改变被磨擦聚酰亚胺膜的表面形态.
