本文採JKR黏著接觸試驗的方式，量測位移、載重和接觸面積，並利用能量差異法分析試體之黏著能，分別量測以聚二甲基矽氧烷(PDMS)製作之平面試體與具有表面微結構之試體，探討此法之適用性。並將量測分析所得之黏著能與最大拉拔力法和JKR法換算之黏著能作比較，對大部分情況而言，由實驗結果得知三種方法所計算之黏著能結果非常接近。然而，能量差異法較適合運用於加載與減載曲線遲滯圈大時，加載與減載曲線遲滯圈小時則需要更高精度的位移量測，以避免因勁度的誤差影響黏著能的計算。

In this study, the work of adhesion of flat PDMS samples and PDMS samples with micro-structures were tested by the JKR adhesive contact experiment and analyzed by the method of energy deficit, which requires the measurement of displacement, load, and contact area. The applicability of this method was discussed. The work of adhesion obtained by the method of energy deficit was compared with the value calculated from the pull-off force and the JKR method. The experimental results showed that the values of the work of adhesion obtained from three methods were quite close for most cases. However, we found that the method of energy deficit was good to use in the case of large hysteresis between loading and unloading curves. When the hysteresis is small, more accurate displacement measurement is acquired to avoid the error in the calculation of stiffness, which will affect the calculation of the work of adhesion.
