Hydrophobic recovery in ultrathin PDMS-coated long and short silicon nanowires

- Method to obtain wide ranges of water contact angles (CA) ∼5° to ∼149° proposed.
- Reported effect of length of silicon nanowires and/roughness on final water CA.
- Reported how nanoscale variation in PDMS thickness effects hydrophobic recovery.
- Studied evolution of water CA vs. time for PDMS coated Si/Si nanowire samples.
