Costly effective superhydrophobic glass surface by deposition of modified homemade pyrophyllite nanosilica has been done. The thin layer coating was deposited on glass substrate by means of spin coating technique with further thermal annealing process. SEM images show the different topography of the surface layers as well as nanosilica layer thickness in the range of 7 to 19?μm. The optimum water contact angle of 142.54° is obtained for the nanosilica coating annealed at 65°C. The presence of the CH, OH, Si-O-Si, and Si-C secondary phases is discussed based on FTIR data analysis. © 2016 AIP Publishing LLC.
