采用具有较大弹性弹簧常数的悬臂梁（施加的力为微牛顿尺度），在原子力显微镜（AFM）的接触模式下对聚碳酸酯（PC）表面进行单次扫描测试。这种方法被用作一种新的纳米加工技术，用于形成类似于传统的正弦结构的三维（3D）聚合物束结构。分析了进给量、法向载荷等加工参数对束结构形成、周期和高度的影响。此外，还研究了针尖几何形状对显微组织形成的影响。
A cantilever with a larger elastic spring constant (the applied force is at the micro Newton scale) is employed to perform a single scanning test on the polycarbonate (PC) surface in contact mode of Atomic Force Microscope (AFM). This method is used as a novel nanomachining technique for the formation of three-dimensional (3D) polymer bundle structures similar to conventional sinusoidal structures. Effects of machining parameters such as the feed and the normal load on bundles formation, the period and the height of bundle structures are analyzed. Furthermore, influence of the tip geometry on microstructures formation is also studied.
