Hydrophobic surface is a surface that has the ability to repel water [1]. The term hydrophobicity was derived from two Greek words that are hydro that means water and phobos that means fear; thus, hydrophobic surfaces can be define as material that tend to repel with water.
What is an example of a hydrophobic surface in nature?
The most famous example of natural superhydrophobic surfaces are lotus leaves (Nelumbo nucifera), which are characterized by θw > 150°, ultra-low water adhesion (ultra-low H and α) and self-cleaning properties [15] (Fig. 2).
How do you make a hydrophobic surface?
These techniques include chemical etching, solution immersion, laser electrodeposition, template deposition, spray coating, various others. Important characteristics of super-hydrophobic surfaces like durability, storability, corrosion resistance, etc. are achieved differently by different methods.
