Robust and antireflective superhydrophobic surfaces prepared by CVD of cured polydimethylsiloxane with candle soot as a template

Taking candle soot as a template, cured polydimethylsiloxane (PDMS) is firstly used for CVD at a high temperature in air to create robust and antireflective superhydrophobic surfaces. No organic solutions or chemical modification is needed. Three-phase lines of the surface are studied by observing the light projection view.
