Self-cleaning capability using a super-hydrophobic coating of silicon dioxide nanoparticles

For practical studies, ultra-hydrophobic coatings are prepared using hydrophobic silica nanoparticles. The coating on each substrate shows self-cleaning capability.
many technical problems have emerged by carefully observing and investigating the unusual characteristics of species found

. Among them, the remarkable non-wetting properties of lotus leaves have greatly influenced the minds of students, researchers and industrialists over the past two decades. Due to the high contact angle (> 150 degrees), water droplets can easily roll off the surface of the lotus leaf, resulting in dirt particles.
this self-cleaning lotus effect has attracted great attention in daily life. Many surfaces in daily life end up contaminated due to the accumulation of dust/dirt or air pollution. Their repair wastes a lot of money, labor and energy. Self-cleaning ultra-hydrophobic coatings are one of the best solutions to this problem.
Each coated substrate exhibits ultra-hydrophobicity
In a recent study, hydrophobic silica nanoparticles were impregnated and/or sprayed on motorcycle bodies, building walls, mini-boats, solar panels, window glass, cotton shirts, cloth shoes, paper (notes), metal, wood, sponges, plastic and marble. Each coated substrate exhibits ultra-hydrophobicity, with a water contact angle of nearly 160 degrees and a sliding angle of less than 6 degrees. The self-cleaning properties of ultra-hydrophobic coatings applied to various substrates are fully evaluated.
the study has been published in Progress in Organic Coatings, volume 128.
