Slip flow of diverse liquids on robust superomniphobic surfaces

摘要: Water slips exist over superhydrophobic solid surfaces, but the slip flow of diverse liquids on a single surface has not been deliberately studied to date. Here, we report behavior variety with different tensions and viscosities robust omniphobic surface. This displayed dramatic slippage effect thus high drag reduction efficiency approximately 10-20% for all liquids, depending both liquid viscosity energy. The observed was attributed dual micro/nanostructure low-surface-energy coating.
