JKR理論已被廣為應用於量測材料機械性質及表面黏著力,本文主要目的是建立一套JKR黏著實驗架構並量測聚二基矽氧烷(PDMS)材料的楊氏模數E及表面黏著能W。利用此試驗裝置,可量測玻璃珠與PDMS試體接觸的加載及減載過程中之接觸半徑a與載重P。利用JKR理論分析實驗數據可計算得到PDMS材料的彈性模數E及表面黏著能W。並探討不同試體製程及不同試體厚度H與玻璃球半徑之比值對PDMS材料的彈性模數E與表面黏著能W之影響。
JKR theory has been widely applied to measure the adhesion and mechanical properties of materials. The main goal of this thesis is to setup an experimental apparatus of JKR adhesion test and to measure the work of adhesion W and elastic modulus E of Polydimethylsiloxane(PDMS). Using this JKR apparatus, the contact radius a and load P in the loading and unloading process of the contact between glass ball and PDMS sample were measured. Based on JKR theory, we calculated the elastic modulus E and work of adhesion W of PDMS from the experimental data. The effects of the sample preparing process and the ratio of sample thickness H and radius of glass ball on the elastic modulus E and work of adhesion W were also discussed.
