Abstract
To characterize the effect of shearing on function of fibrillar adhesive microstructure, friction and shear-related changes in pull-off force of a biomimetic polyvinylsiloxane mushroom-shaped fibrillar adhesive microstructure were studied. In contrast to a control flat surface, which exhibited pronounced stick-slip motion accompanied with high friction, the fibrillar microstructure demonstrated a stable and smooth sliding with a friction coefficient approximately four times lower. The structured contact also manifested zero pull-off force in a sheared state, while the flat surface exhibited highly scattered and unreliable pull-off force when affected by contact shearing. It appears that the fibrillar microstructure can be used in applications where a total attachment force should be generated in a binary on/off state and, most surprisingly, is suitable to stabilize and minimize elastomer friction.
摘要
为了表征剪切对纤维状粘性微观结构功能的影响，研究了一种仿生聚硅氧烷蘑菇状纤维状粘性微观结构的摩擦力以及与剪切相关的拉脱力变化。与呈现出明显的粘滑运动并伴有高摩擦力的对照平面不同，纤维状微观结构表现出稳定且平滑的滑动，其摩擦系数约低四倍。结构化接触在剪切状态下也表现出零拉脱力，而平面在受到接触剪切影响时则表现出高度分散且不可靠的拉脱力。看来，纤维状微观结构可用于在二元开/关状态下应产生总附着力的应用中，而且最令人惊讶的是，它适用于稳定和最小化弹性体摩擦。
