Nowadays, everyone will get a two-wheeler or a four-wheeler. Everyone is positive about their car. They always expect high mileage from them. I also want the car to always shine and have no scratches on it. Now a good news has come out which will relieve all the car owners. Researchers at the Korea Research Institute of Chemical Technology (KRICT) have designed a transparent coating material for vehicles. It can self-heal in 30 minutes when exposed to sunlight. This discovery of the researchers is published in the journal ACS Applied Polymer Materials. However, the protective coating usually available for wheels is very durable. It is transparent and colorless to preserve the original color of the product.
The only problem is that this coating gives poor self-healing. However, this is not a problem with the newly developed self-healing coating. The coating prepared by KRICT researchers is durable and transparent and can self-heal after being exposed to sunlight for 30 minutes. Sunlight should have near-infrared light, especially in the 1000 to 1100 nm wavelength range. This helps to self-heal wheel scratches. To test the clear coat, the research team used a coating spray machine to apply the coating to a laboratory car model. After applying the self-healing coating, the wick scratches disappeared completely. Exposing the car to afternoon sunlight, the surface of the coating material was restored within 30 minutes.
There is also a plan to use a self-healing material.
The technique used in the self-healing automotive coating is that the temperature of the surface of the developed material increases when sunlight is absorbed. Because light energy is converted into thermal energy. This leads to repeated breaking and recombination of the chemical bonds in the polymer structure, which is enabled by the increased surface temperature. Ultimately, this leads to self-healing of surface scratches. The research team also plans to use this self-healing material in building materials, electronic devices such as computers and smartphones, and transportation applications. In addition, the use of less harmful organic solvents is expected to help achieve carbon neutrality. These solvents are produced in large quantities during the repainting of rims.
