Mimicry of nature is the easiest way to reproduce superhydrophobic properties because nature has for millennia produced plants, insects and animals able to repel water. The most famous example is the lotus leaf.
SiO2 International Inc. uses natural silicon dioxide in their SiO2 technology to make superhydrophobic coatings just like nature does. SiO2 coatings form a surface structure similar to natural surface structures thus repelling water like many plants leaves, insects and animals.
Superhydrophobicity and self-cleaning properties pick up dirt particles by water droplets due to the micro- and nanoscopic architecture on the surface, which minimizes the droplet’s adhesion to that surface. This self-cleaning effect is of great importance as a protection against pathogens such as viruses, bacteria, molds, etc.
Due to high surface tension, water droplets tend to minimize their surface by trying to achieve a spherical shape (superhydrophobic).
