The main uses of nanomaterials: pharmaceuticals, household appliances, electronic computers, and the electronic industry, environmental protection, textile industry, and machinery industry.
Nanotechnology is the core technology in the development of automobiles. Nanotechnology can be applied from car bodies to wheels, covering almost all of cars. The widespread application of nanotechnology in automobile industry will reduce the wear of various parts of automobiles, reduce automobile consumption, and reduce the cost of using automobiles; To some extent, it can also eliminate vehicle exhaust pollution and improve emissions. Nowadays, many automotive products have begun to adopt nanotechnology, and small nanometers will bring great changes to automobiles.

Application of nano material technology in the automotive industry: automotive baking paint coatings, automotive plastic rubber, automotive exhaust catalyst materials.

Automotive baking varnish coatings: The peeling and aging of automotive baking varnish are the main factors causing the deterioration of automotive aesthetics, with aging being a difficult and difficult variable to control. There are many factors that affect the aging of baking varnish, but the most critical one is ultraviolet rays in the sun. Ultraviolet rays can easily break the molecular chains of materials, leading to aging of material properties. For polymer plastics, as well as organic coatings, ultraviolet rays are the most aggressive of all factors for organic coatings. Therefore, if the effect of ultraviolet rays can be avoided, the aging resistance of baking varnish can be greatly improved. Currently, the most effective material for shielding ultraviolet rays is nano titanium dioxide nanoparticles.
TiO2 nanoparticles are one of the main nanomaterials developed in the late 1980s. The optical effect of nano TiO2 varies with particle size, and nano rutile TiO2 has a color change effect with angle, making it the most important and promising modifier in automotive baking varnish. The shielding of nano TiO2 against ultraviolet rays is mainly scattering, and particle size is one of the important factors affecting the scattering ability.
Automotive plastic rubber: The amount of plastic used in automotive manufacturing is increasing. Nanoplastics can change the characteristics of traditional plastics and exhibit excellent physical properties: high strength, strong heat resistance, and a smaller specific gravity. Because the size of nanoparticles is smaller than the wavelength of visible light, nanoplastics can exhibit good transparency and high glossiness, and such nanoplastics will have a wide range of applications in automobiles.

The largest amount of rubber used in automobiles is tires. In the production of tire rubber, most of the rubber additives are in the form of powders, such as carbon black, white carbon black, and other reinforcing fillers, accelerators, and antioxidants. In terms of powdery materials, nanometerization is the main development trend at this stage. The new generation of nanotechnology is no longer limited to the use of carbon black or white carbon black, such as nano alumina, nano titanium dioxide, and the successful use of other nanoparticles as additives. The biggest change is that the color of tires is no longer limited to black, but can have a variety of bright colors. In addition, no matter in strength, wear resistance or anti-aging performance, the new nano tire is superior to the traditional tire. Research data shows that the crack resistance of automobile tire side rubber will be improved from 100000 times to 500000 times by adding nano coatings such as nano, nano alumina, nano titanium dioxide, etc.

Automotive exhaust catalyst materials: The problem of automotive exhaust pollution is becoming increasingly serious, and installing catalyst converters is currently the main way to solve automotive exhaust pollution. Traditional catalysts for automotive exhaust purification use platinum, palladium, and rhodium as ternary catalysts, but they are scarce in resources, difficult to obtain, and expensive; It is prone to lead, S, and P poisoning, resulting in catalyst failure and other characteristics. Using nano titanium dioxide  and nano alumina as nano carriers can reduce the amount of precious metals platinum, palladium, and rhodium, and improve catalytic efficiency.
