What Are the Key Mechanisms Behind Nanotechnology-Based Anti-Fog Coatings?
There are primarily two mechanisms by which nanotechnology-based anti-fog coatings work:
Hydrophilic Coatings: These coatings attract water molecules and spread them into a thin, uniform layer that does not scatter light, thus maintaining transparency. Hydrophilic coatings often use materials like titanium dioxide (TiO2) nanoparticles. Hydrophobic Coatings: In contrast, hydrophobic coatings repel water, causing it to form droplets that easily roll off the surface. This effect is often achieved by creating a superhydrophobic surface with nanostructures that mimic the lotus leaf.
