Effects of calcination temperature on the microstructure and wetting behavior of superhydrophobic polydimethylsiloxane/silica coating

- The superhydrophobic coating was fabricated by spraying the PDMS and nano-SiO2.
- The coating showed various microstructure and wettability by adjusting calcination.
- After calcining at 400 °C, the superhydrophobic coating became highly transparent.
- The calcination mechanism of the PDMS/SiO2 coating was proposed.
