To provide a new approach for further improvement of friction-reducing properties of surfaces which are in contact with or are intended to be brought in contact with a liquid.SOLUTION: A structured surface at least partially comprises liquid-repelling structures and, under liquid, at least temporarily holds or can hold a gas layer. The structured surface additionally comprises projecting longitudinal structures parallel to the flow direction of the liquid, or parallel to the movement direction of the structured surface relative to the liquid. The projecting longitudinal structures project at least temporarily by 0.1 μm to 10 mm from the gas layer into the liquid.SELECTED DRAWING: Figure 1
【課題】液体と接触状態にある又は液体と接触させられることが意図される表面の摩擦低減特性を更に改善するための新しい手法を提供する。【解決手段】液体をはじく構造を少なくとも部分的に備え、液面下でガス層を少なくとも一時的に保持する又は保持することができる構造化表面であって、前記液体の流れ方向に平行な又は前記液体に対する該構造化表面の移動方向に平行な突出する長手方向構造を更に備え、前記突出する長手方向構造は、前記ガス層から0.1μm~10mmだけ少なくとも一時的に突出し、前記液体に入る。【選択図】図1
