Nanocoatings are thin films or layers that are applied to a surface to change its characteristics and are measured in nanometers (one billionth of a metre). Nanomaterials, or substances having particles smaller than 100 nanometers in at least one dimension, are used to create these coatings.
To improve a surface's characteristics, a thin coating of a nanoscale substance is applied. Many methods, including electroplating, sol-gel deposition, physical vapour deposition (PVD), and chemical vapour deposition (CVD), can be used to create nanocoatings. Usually applied to a substrate material like glass, metal, or plastic, the nanoscale substance utilised in nanocoating might be metallic, ceramic, or polymeric. The surface qualities of the substrate material can be improved in a variety of ways by the nanocoating layer, which can be as thin as a few nanometers. Increased hardness, scratch resistance, corrosion resistance, and anti-fouling qualities are a few advantages that nanocoatings may offer. For instance, a nanocoating layer can stop dirt, dust, or germs from building up on a surface, making it simpler to clean and maintain. There are various types of nanocoatings, including: Anti-reflective coatings: The anti-reflective coating allows more light to travel through the glasses lens as opposed to reflecting off of it, which minimises reflected light. This implies that the front or rear surfaces of your lenses will have little to no reflections. Anti-corrosion coatings: For components working in severely corrosive environments, anti-corrosion coatings offer a strong level of corrosion protection. Although there are many alternatives for anti-corrosion coatings, they may be divided into three basic categories: barrier, inhibitive, and sacrificial. Self-cleaning coatings: Water and other liquids can be repelled by these coatings, which can aid in preventing dirt and other impurities from sticking to the surface. Anti-fouling coatings: Anti-fouling paint is a specific class of coatings that is put as the top layer to the hull of a ship or boat to help subaquatic organisms that cling to the hull develop more slowly and detach more easily. These organisms can negatively impact a vessel's performance and durability. Anti-microbial coatings: The use of a chemical substance known as an antimicrobial coating prevents the spread of the disease-causing microorganism. Antimicrobial coatings offer protection against a wide range of bacteria, mould, and mildew, in contrast to other coatings that offer anti-corrosion resistance capabilities. Superhydrophobic coatings: A thin surface layer that deflects water is known as a superhydrophobic coating. It is constructed of superhydrophobic (ultrahydrophobicity) substances. This type of coating allows droplets to fully rebound after impact. Conductive coatings: Advanced materials called conductive coatings, which may be applied as paint, spray, or laminate, are capable of conducting an electrical current. It can be sufficient to apply a tiny coating of this to a certain area of your aircraft to boost its conductivity. Thermal barrier coatings: Advanced materials known as thermal barrier coatings (TBCs) are employed as coatings on aviation engines or turbines to protect the materials from overheating during high-temperature procedures. Common oxides used as TBCs include yttria-stabilized zirconia (YSZ). Magnetic coatings: These coatings have the ability to magnetically modify surfaces, which can be advantageous for uses like data storage.
