In modern mechanical design, non-sticky and non-slippery surfaces are highly preferred in many applications. In this work, bio-inspired micro patterns of hexagonal pillar and round dimple with various geometric parameters are fabricated, and the static friction and adhesion performances of the prepared surfaces are investigated. It is found that hexagonal pillar patterns can enhance the static friction and weaken the adhesion performances either at dry or wet conditions. The effects of round dimple patterns on the tribological performances depend on the wetting condition, the load, and the area density. The function mechanism of the designed surfaces is revealed, and a general design principle of the biomimetic patterned surface is proposed.

非粘性和防滑仿生图案表面

在现代机械设计中，在许多应用中高度首选不粘和不滑的表面。在这项工作中，制造了具有各种几何参数的六角柱和圆形酒窝的生物启发性微图案，并研究了所制备表面的静摩擦和粘附性能。发现六边形柱状图案可以在干或湿条件下增强静摩擦并削弱粘附性能。圆形酒窝模式对摩擦学性能的影响取决于润湿条件，载荷和面积密度。揭示了设计表面的功能机理，提出了仿生图案表面的一般设计原理。
