已经研究了各种生物启发的干粘合剂材料。本文采用光刻和硅深腐蚀方法制备了仿生微柱干胶材料，并对生物微柱干胶材料的边长、高边长比（HSAR）和柱间距边长比（DSAR）等参数进行了综合研究，以获得高附着力的干胶。通过正交试验设计和一系列的制备实验确定了最佳工艺参数，得到了2.98 N·cm-2的法向附着力和9.59 N·cm-2的剪切附着力。在此基础上，设计了一种新型的附着与脱附装置，使无人机能够成功地附着与脱附在天花板上。这将使无人机能够长时间停留在空中，这对许多应用来说都是非常宝贵的，例如节能和空中探测。
Various bio-inspired dry adhesive materials have been investigated. In this work, lithography and silicon deep etching method were used to fabricate bio-inspired micro-pillar dry adhesive materials of which the parameters, such as side length, Height to Side length Aspect Ratio (HSAR), and inter-pillar Distance to Side length Aspect Ratio (DSAR) were comprehensively studied to obtain a dry adhesive with high adhesion. An orthogonal array method was designed and a series of fabrication experiments were conducted to identify optimum parameters, which resulted in a high normal adhesion of 2.98 N·cm‒2and a shear adhesion of 9.59 N·cm‒2. An adhesion and desorption device was further designed on basis of the optimum dry adhesive, which enables an Unmanned Aerial Vehicle (UAV) to successfully adhere on and detach from a ceiling. This would allow an UAV to stay aloft for prolonged time, which could be invaluable to many applications, such as energy conservation and aerial detection.
