The invention discloses a rapid long-distance self-guiding surface of a patterned arrow structure liquid drop. The rapid long-distance self-guiding surface comprises a substrate and a surface microstructure on the substrate, the surface microstructure comprises a plurality of microstructure units which are arranged in a linear array; each microstructure unit comprises a plurality of microstructure bodies which are connected end to end and are arranged in a linear array; the single microstructure body is of an arrow-shaped structure, and spreading of liquid is promoted in the arrow direction; in the opposite direction of the arrow, the spreading of the liquid is inhibited; the self-guiding surface shows a good self-guiding effect on liquids such as pure water and seawater, and the difficulty of processing and manufacturing is low due to the two-dimensional structure. 一种图案化箭头结构液滴快速长距离自引导表面，包括基底及在基底上的表面微结构；表面微结构包括若干微结构单元，若干微结构单元呈线性阵列设置；每个微结构单元包括若干个微结构体，若干个微结构体首尾相接呈线性阵列设置；单个微结构体呈箭头状结构，在箭头方向，液体的铺展受到促进；在箭头的反方向，液体的铺
