The　tunable　of　fluid　transport　on　solid　surface　plays　a　significant　role　for　self-cleaning　and　drug-saving　fields.　It　effectively　prevents　the　corrosion　and　declines　the　fluid　resistance　induced　by　the　rushing　water　and　accumulated　microorganisms　on　the　hull　surface.　To　more　effectively　combat　these　problems,　herein,　we　provide　a　new　strategy,　a　superhydrophobic　shark-fin-like　bionic　surface.　Anisotropic　characteristic　of　this　novel　structure　lead　to　the　different　de-pinning　force　in　the　opposite　direction　for　the　water　droplet.　The　superhydrophobicity　of　the　shark-fin-like　embossment　is　from　the　＂air　layer＂　formed　by　the　ZnO　nano-structure.　This　novel　composited　surface　can　effectively　realize　the　directional　droplet-actuation　and　fluid-resistance　reduction　performance.　Droplets　and　fluid　will　move　more　easily　along　the　special　direction　on　the　shark-fin-like　surface.　Moreover,　the　substrate　material　is　flexible　and　easy　to　mass　production.　We　believe　that　this　work　will　give　a　significant　scientific　insight　to　self-cleaning　surface　and　hull　design.　(C)　2019　Taiwan　Institute　of　Chemical　Engineers.　Published　by　Elsevier　B.V.　All　rights　reserved.
