I. What is a nano coating?
Nanocoatings refer to coatings in which nanomaterials (particle size 1–100 nm) are introduced or nanostructures are constructed, endowing the coating with special functions not possessed by conventional paints. The quantum size effect, surface effect, and macroscopic quantum tunneling effect of nanomaterials enable the coating to exhibit unique properties in optical, electrical, thermal, and mechanical aspects.
II. Nano Self-Cleaning Coating
Based on two technical approaches:
- Superhydrophilic type (photocatalytic): Using nano-TiO₂ as the core material, a photocatalytic reaction is generated under ultraviolet light irradiation to decompose organic pollutants, while the surface becomes superhydrophilic, allowing rainwater to spread evenly and wash away stains. Suitable for glass curtain walls, solar panels, etc.
- Superhydrophobic type (lotus effect): Mimicking the micro-nano composite structure of lotus leaf surfaces, with a contact angle >150°, water droplets roll off in a spherical shape and carry away dust. Suitable for building exterior walls, bridges, transportation facilities, etc.
III. Nano Thermal Insulation Coating
Utilizing the selective reflection and absorption properties of infrared by materials such as nano antimony tin oxide (ATO) and nano indium tin oxide (ITO) to achieve transparent thermal insulation. Applied to architectural glass and automotive glass, it can lower indoor temperature by 5–8°C in summer and reduce air-conditioning energy consumption by 20–30%.
IV. Nano Anti-Corrosion Coating
Utilizing nano-platelet fillers (such as nano micaceous iron oxide, graphene, etc.) to create a "labyrinth effect" within the coating, greatly prolonging the permeation path of corrosive media and enhancing anticorrosion performance by 3 to 5 times. Meanwhile, nanomaterials can fill the micropores of the coating, improving its density and adhesion.
