This paper suggests a testing method to measure the frequency-domain viscoelastic properties of a micron-scale thickness adhesive. To test a thin adhesive below room temperature, a new double-shear tester is designed in this study. A thin pressure-sensitive adhesive (KGK-200A50) with the thickness of 50 μm is tested in the range of \(-5.5\ ^{\circ}\mbox{C}\)–\(16.4\ ^{\circ}\mbox{C}\) and 0.1 Hz–5 Hz. The measured storage and loss modulus are found to vary between 15 kPa–226 kPa and 31 kPa–301 kPa, respectively, and over the full range of frequency and temperature investigated. A time–temperature superposition is applied to derive higher-frequency viscoelastic properties with the extended frequency range of 0.1 Hz–2000 Hz at \(16.4\ ^{\circ}\mbox{C}\). The experimental results are found to be overall in good agreement with other published results.

本文提出了一种测量微米级厚度粘合剂的频域粘弹性质的测试方法。为了在室温下测试稀薄的粘合剂，本研究设计了一种新的双剪切测试仪。在\（-5.5 \ ^ {\ circ} \ mbox {C} \） – \（16.4 \ ^ {\ circ}的范围内测试了厚度为50μm的薄压敏粘合剂（KGK-200A50）\ mbox {C} \）和0.1 Hz-5 Hz。发现在整个研究的频率和温度范围内，测得的储能模量和损耗模量分别在15 kPa–226 kPa和31 kPa–301 kPa之间变化。在（（16.4 \ ^ {\ circ} \ mbox {C} \）处，应用时间-温度叠加来导出具有0.1 Hz-2000 Hz扩展频率范围的高频粘弹性质。发现实验结果总体上与其他已发表的结果一致。
