The application of nanocomposites in the automotive industry

nanotechnology has aroused great interest in the past ten years. As a branch of nanotechnology, nanomaterials have also received extensive research, and led to the development, production and commercialization of new materials. The automotive industry is one of the many application fields of nanocomposites, and the components of nanocomposites are being applied in the automotive industry

(I) comprehensive research

nanocomposites are defined as containing nano fillers in solid matrix (usually polymers), which are called nano materials (such as nanoparticles, nanotubes, nanofibers, etc.). Nano materials are the basis of nanocomposite components in automobile manufacturing

1. Characteristics of nano materials

① it increases the contact area between the particle and its surrounding environment, and can continue to show its good performance under ultra-high temperature, which intensifies the interaction between the particle and the surrounding matrix, and improves the mechanical properties of the material. The mechanical, chemical and thermal properties of the material (1g25nm particles have a surface area of 20m2)

② transparency: when the particle size is less than 30nm, the reflection of visible light can be ignored

2. Access to nano materials

first, it is a top-down approach, which is characterized by making it "small" from "big", such as the method used in the semiconductor industry; Another bottom-up approach is characterized by assembling atoms or molecules into substances, such as the method used in the chemical industry

3. The application of nano material products in various functions in the automotive industry:

① it is used to prepare the fuel catalyst carrier in the particulate filter to prevent smoke

② the tire reinforced by nanoparticles has better wear resistance and air permeability

③ used in automobile coating, showing excellent scratch resistance and improving surface gloss

④ high hydrophilic antifogging coating for headlights and windscreens, forming a water film rather than water droplets

⑤ it is used for light structural plastic parts with better mechanical properties and heavier weight. Customers don't understand our detailed technical support to customers
