Papillaes-enhanced hydrophobicity of large-sized polytetrafluoroethylene-polyphenylene sulfite soft film prepared by layer-by-layer construction

► We reported a low-cost and economical method to fabricate a large size of superhydrophobic soft film ► Our method may be developed into a good strategy to construct special functional surfaces ► Our manuscript shows a novel method to prepare Cassie-type surface by combining natural micro-nanostructure units.
