[China Aluminum Network] Japanese scientists have developed a new coating material that can quickly repair surface flaws. The test confirmed that this material can completely repair the cuts and scratches, and can be used in the production of automotive surface film coatings and other fields. Experts said that this material can also be used in the manufacture of medical products such as hemostatic stickers for internal organs, and researchers will strive to realize their commercialization at an early date.
The team at Osaka University in Japan announced recently that they have developed a new coating material that can quickly repair surface flaws. The test confirmed that this material can completely repair the cuts and scratches, and can be used in the production of automotive surface film coatings and other fields. The team led by Prof. Harada Harada of the school completed related research and development work. The specific results were published on the electronic version of the well-known American scientific journal on November 11, 2016.
Materials known as "self-healing materials" are often used in the painting of high-end automobiles, screen protection of smart phones, and the like. However, there are deficiencies in previous products, such as the inability to completely repair the wound or the repair takes too long.
The team developed a special polymer with a large number of cyclic molecules passing through long strips of molecules. The annular part is free to move and reacts to the broken parts, allowing the macromolecules to bond together again, thus successfully repairing scars and depressions. The researchers produced the material as freeze-dried and film-like materials. When confirming their properties, the jelly-like material was able to repair 80% of the wound within 10 minutes, while the film-like material achieved a complete 30-minute repair of the wound.
Experts said that this material can also be used in the manufacture of medical products such as hemostatic stickers for internal organs, and researchers will strive to realize their commercialization at an early date.
