摘要：
受生物启发的结构粘合剂在攀爬机器人、医疗设备等诸多应用中受到越来越多的关注。受树蛙趾垫上紧密排列的角蛋白纳米柱启发，研究人员通过模具工艺和化学改性制备了排列紧密的聚己内酯纳米棒阵列。与带有六边形微柱的阵列相比，纳米棒阵列在光滑和粗糙表面上均表现出增强的粘附力和摩擦力。纳米棒的结合使纳米棒表面具有更大的刚度，这主要对摩擦力而非粘附力有贡献。该结果揭示了树蛙趾垫上紧密排列的角蛋白纳米柱的功能，并为设计具有强附着能力的新型结构粘合剂提供了指导原则。
英文摘要：
Bioinspired structure adhesives have received increasing interest for many applications, such as climbing robots and medical devices. Inspired by the closely packed keratin nanopillars on the toe pads of tree frogs, tightly arranged polycaprolactone nanorod arrays are prepared by mold process and chemical modification. Nanorod arrays show enhanced adhesion and friction on both smooth and rough surfaces compared to the arrays with hexagonal micropillars. The bonding of nanorods results in a larger stiffness of the nanorod surface,contributing mainly to friction rather than adhesion. The results suggest the function of closely packed keratin nanopillars on the toe pad of tree frogs and offer a guiding principle for the designing of new structured adhesives with strong attaching abilities.
