Application of Nanoparticles for Self-Cleaning Surfaces
Self-cleaning in one of the most significant applications in the recent years to repel the contaminants like dirt, toxic pollutants, and microbes from any kind of surface. Hydrophobic and hydrophilic coatings are commonly used to fabricate a self-cleaning surface. Nanoparticles play a vital role in the design of self-cleaning glasses/goggles, windows, paints, building materials, medical devices, fabrics, and corrosion resistance materials. The basic principles, various applications, and key findings of hydrophobic/super-hydrophobic and hydrophilic/super-hydrophilic coated substrates are briefly discussed in this chapter. The utilization of different self-cleaning products available in the market is also highlighted. Moreover, the future challenges are described to fabricate an eco-friendly, cost-effective, highly stable, and durable self-cleaning surface.
