Simple fabrication approach for superhydrophobic and superoleophobic Al surface
Superhydrophobic and superoleophobic Al surface is demonstrated. Simple microfabrication contains mechanical grinding, acid etching, and FOTS coating. Addition of grinding step improves the rolling behavior of droplets. Grinding process induces mechanical defects and accelerates etching reaction.
