ABSTRACT

The present paper demonstrates the possibility of the use of atomic force microscopy (AFM) to study the morphology of elastomeric materials under stretching. A prototype of a stretching device that could be integrated into AFM for the tensile drawing of polymer at different temperatures including low temperature was constructed. As a trial sample for testing the prototype of low temperature stretching device nitrile butadiene rubber (NBR) was selected. The strain-induced morphological changes of neat NBR and NBR with plasticiser were studied. Poisson's ratio and average surface microroughness at different temperatures and strains are measured.

原子力显微镜在弹性材料低温应变研究中的应用

摘要

本论文展示了使用原子力显微镜 (AFM) 研究弹性材料在拉伸下的形态的可能性。构建了一个可以集成到 AFM 中的拉伸装置原型，用于在包括低温在内的不同温度下拉伸聚合物。选择低温拉伸装置丁腈橡胶（NBR）作为试验样品。研究了纯丁腈橡胶和含增塑剂丁腈橡胶的应变诱导形态变化。测量了不同温度和应变下的泊松比和平均表面微粗糙度。
