CTOnews.com, July 22 (Xinhua)-- Hyundai Motor Group unveiled six new nanotechnologies at its Nano Tech Day event on Thursday, which is expected to be a key driver of future growth in the automotive industry.

"in the automotive field, only through the development of state-of-the-art material technology can the performance and durability of automotive parts be improved, which will provide a competitive advantage in the fast-growing future mobile market," Lee Jong-soo, vice president of Hyundai Automotive Group Advanced Technology Development Research Institute, said at a news conference in Seoul.

The nanometer is 1/1000000000 meters, which is equivalent to 1/100000 of the thickness of human hair.

Modern automobile continues to develop and promote nanotechnology to synthesize substances and control the arrangement in such a small unit, so as to produce materials with new properties.

Hyundai Automobile has launched six key nanomaterial technologies: self-repairing polymer coating, oil capsule polymer coating, transparent perovskite solar cell, series solar cell, varistor material and transparent radiation cooling film. CTOnews.com summarizes according to the report as follows:

Self-repairing polymer-coated cars can repair their own scratches and restore the surface to their original state in a few hours, removing scratches or water from cameras and lidar sensors on self-driving cars.

This technique takes advantage of the characteristics of the self-repairing material, in which the split polymer in the coating undergoes a chemical reaction to restore its original state when it is scratched.

Hyundai is considering applying the technology to the surfaces of camera lenses and LiDAR sensors used in self-driving cars.

Series solar cells introduced in the event "series solar cells" are produced by combining the next-generation solar material perovskite with silicon solar cells. More than 35% energy efficiency can be achieved by stacking two solar cells that absorb sunlight in different spectral ranges.

Hyundai believes that by applying tandem solar cells to areas exposed to direct sunlight, such as engine covers, ceilings and doors of environmentally friendly cars, it will be possible to generate enough electricity for daily driving.

The goal is to provide an additional 20 kilometers of mileage per day through the use of solar energy.

Transparent radiation cooling film can be used in vehicle glass, which can reduce the interior temperature even in hot weather without energy consumption.

This technique takes advantage of the decrease in temperature when the radiant heat emitted by an object is greater than the radiant heat absorbed.

Oil capsule polymer coating uses nanocapsules to reduce component wear.

Transparent perovskite solar cells can be used in all windows that require transparency, such as cars and buildings.

Varistor material varistor material can convert pressure energy into electronic signal without sensor. It can be used in the car seat, heating only the part of the seat that touches the passenger's body.
