论文摘要
在这项研究中，研究了壁虎启发的粘合剂垫的粘附性 - 粘附性行为，以了解壁虎脚粘附的开/关开关机理。使用有机硅橡胶制造了宏观刮刀模型，并进行了侧面滑动和垂直剥离的粘附测试。据观察，垫子的接触状态和垫子的粘附力在脱束之前的侧面滑动方向有很大变化，并且即使由于过量的侧面滑动而失去接触时，垫子在剥离过程中也达到了粘附。这些结果解释了壁虎脚的开/关开关和稳定粘附的背后的机制，并提出了开发能够切换粘附的新代粘合剂的可能性。
In this study, the adhesion-detachment behaviour of a gecko-inspired adhesive pad was investigated to understand the on/off switching mechanisms of adhesion in gecko feet. A macroscopic spatula model was fabricated using silicone rubber, and adhesion tests combining lateral sliding and vertical debonding were conducted. It was observed that the contact state and the adhesion force of the pad vary considerably with the direction of lateral sliding prior to debonding, and that the pad achieves adhesion during debonding even when it loses contact due to excess lateral sliding. These results explain the mechanisms behind the on/off switching and stable adhesion of gecko feet, and suggest the possibility of developing new-generation adhesives capable of switchable adhesion.
