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.
