The octopus is capable of adhering to slippery, rough, and irregular surfaces in the marine intertidal zone because of its periodic infundibulum-shaped suckers on the arms. Here, we present a scalable self-assembly technology for fabricating adhesion materials that mimic octopus sucker functionality. By utilizing spin-coated two-dimensional colloidal crystals as templates, non-close-packed nanosucker arrays are patterned on silicone substrates. The resulting nanosuckers can be deformed to exhibit great adhesive capacities on both microrough and flat surfaces in dry and wet environments. This indicates a probable biomimetic solution to the challenge of wound care.
章鱼由于其臂上周期性的漏斗形吸盘，能够附着在海洋潮间带的光滑、粗糙和不规则表面上。在这里，我们提出了一种可扩展的自组装技术，用于制造模仿章鱼吸盘功能的粘附材料。通过利用旋涂二维胶体晶体作为模板，在硅酮基底上形成非密堆积纳米吸盘阵列。得到的纳米吸盘在干燥和湿润环境中都可以变形，在微粗糙和平整表面上表现出很强的粘附能力。这为伤口护理的挑战提供了一种可能的仿生解决方案。
