Both transparent and non-transparent self-cleaning surfaces are highly desirable as they offer many advantages, and their potential applications are endless. The self-cleaning mechanism can be seen in nature. The Lotus flower, a symbol of purity in Asian cultures, grows in muddy waters, but it stays clean and untouched by dirt, organisms, and pollutants. The Lotus leaf self-cleaning surface is hydrophobic and rough, showing a multi-layer morphology of nanoscaled roughness. While hydrophobicity produces a high contact angle, the surface morphology reduces the adhesion of water drops to the surface, which slides easily across the leaf surface carrying the dirt particles with them. Different ultra-hydrophobic, non-transparent, and transparent coatings, for potential self-cleaning applications, were produced on polycarbonate (PC) substrates, using hydrophobic chemistry and different configurations of roughening micro- and nano-particles. However, in most cases, these coatings present low adhesion and durability. The stability and durability of the ultra-hydrophobic surfaces is of key importance for potential, commercially viable, self-cleaning applications thus durability and stability enhancement of such coatings was attempted by different methods, evaluated, and eventually improved using a solvent-bonding technique.
