S
uperhydrophobic surfaces have recently attracted a lot of attention due to their high water repellency along with a wide range
of applications in many fields. The application of such surfaces for self-cleaning purposes, such as in solar cell modules, has
been limited due to the lack of mechanical robustness, thermal stability and ultraviolet radiation resistance. The fabrication
of superhydrophobic water-repellent surfaces with mechanical robustness and high transmittance remains a major challenge.
The focus of this work is to prepare highly transparent water-repellent surfaces with improved mechanical stability/robustness
by simple spray coating process. The developed coating solution can be sprayed on all kinds of materials surfaces to create a
superhydrophobic self-cleaning surfaces. Proper molar ratios of Methyltrimethoxysilane (MTMS) and (3-Glycidyloxypropyl)
trimethoxysilane (GLYMO) are used to bond the functionalized silica nanoparticles to various substrates and promote
robustness. Optimum spraying cycles (layers) of 1.0%wt SiO

nanoparticles after adhesive layer has resulted in contact angles
of the order of 170° with a hysteresis of 6° and sliding angle of 1°. Developed surfaces also exhibited excellent stability under
simulated outdoor conditions, such as pressurized jet water, abrasion and ultraviolet radiations etc. Improvement of surface
transmittance was achieved by annealing the surface under temperatures up to 300°C without losing superhydrophobicity.
The optical transmittance of the optimum annealed surface varied between 75% of that of virgin glass, at the visible light
wavelength of 400nm and 90% at 800nm. The developed surface during this research makes them a promising candidate for
outdoor self-cleaning applications even under harsh environmental conditions.
