Wetting behavior of microgroove and micropillar patterned surface

Lotus effect is the natural phenomena where superhydrophobicity can be detected on the outside of a lotus leaf. This is due to the micro protrusions and wax nanocrystals that are present on the outside of a lotus leaf. If observed carefully, the protrusions are like micro pillars. In similar way, another natural superhydrophobic surface is the paddy leaf. When zoomed in oe natural examples, microgroove and micro pillared surfaces are fabricated to conduct wetting study with the idea of achn the surface, there are groove like structures that slide down the water without actually wetting the leaf. Taking the abovieving hydrophobicity on a metal surface that can be used in engineering of various products where it is necessary to have the water not staying at a point. This paper highlights the construction of the two surfaces and conducting wetting study. An ideal ridge width to channel width ratio and optimized microstructure is found to support hydrophobic nature in the surface.
