Abstract

A mechanical model analysis was conducted to evaluate quantitatively spring constants for cantilevers and polymer surface via scanning viscoelasticity microscopic (SVM) measurement. The amplitude of dynamic displacement was set to be 5 nm, and the frequency was varied in the range of 10¹ - 2×10³ Hz. Under such the condition, the cantilevers and the polystyrene (PS) surface exhibited elastic nature. An analysis using mechanical model could well reproduce the experimental results. Based on fitting parameters for the analysis, the spring constants for the cantilevers and the PS surface were extracted. Finally, it was concluded that surface mechanical properties in polymer films would be essentially different from the corresponding bulk ones.
