After the protective coating is broken, it automatically heals and restores the self-healing material to open up commercial applications

The idea that synthetic protective coating materials can heal slowly like wounds is now a reality. At the 4th Military-Civilian Fusion Development High-Tech Equipment Achievement Exhibition, Li Guoliang research team of the Institute of Process Engineering of the Chinese Academy of Sciences developed a "magic powder" - "Jufu Shield" for Shandong Gig New Materials Technology Co., Ltd.as an intelligent nano-coated material additive, poly-composite shield can repair itself after the metal coating is broken, and continues to provide corrosion protection for metal surfaces such as aircraft and ships . At present, BAIC Taipu off-road vehicles, Lingyun Technology and other enterprises signed the "Jufu Shield" application agreement, this self-healing material officially commercialized."Poly-composite shield" to poly-composite materials as the core technology, the use of foreign aid-type self-healing technology, simulation of biological damage self-healing principle, to achieve the rapid recovery of coating materials themselves and interface defects, not only can extend the life and maintenance cycle of the metal material body, effectively reduce the accident rate caused by corrosion, but also compared to the traditional coating material used to prevent corrosion of the toxic substance hexavalent chromium salt, but also greener and safer. Therefore, in marine engineering, modern transportation, machinery and equipment, energy industry, aerospace and many other fields, there is room for it to expand.After the "Polydrive Shield" products are put on the market, they will not only provide important technical support for the improvement of the quality of heavy anti-corrosion projects such as Chinese military ships, civilian vessels, oil exploration and transportation, and offshore drilling, but also provide new solutions to the safety and economic problems caused by metal corrosion.self-healing materials is a cutting-edge subject that the international materials academic community has been exploring for many years. In recent years, many basic academic papers in this field have been published, but industrialized and commercialized repairable materials are still the unrealized dreams of many scientists.2011

to 2014
, Li Guoliang, a postdoctoral student at the Mapu Institute of Collomes and Interfaces in Germany, came into contact with the cutting-edge ideas of self-healing nanomaterials.
2015
, Li Guoliang joined the Chinese Academy of Sciences and decided to put aside his previous thinking and redesign the experimental route in his own way. More than ten years of experience in nano-polymer materials research have given him new inspiration.Li Guoliang designed a new preparation technology to add foreign aid-type intelligent nano-microballs to the corrosion protection coating material. After cracks or mechanical damage to the material, nano-microballs will sense changes in the environment and release repair agents to the damaged surface in a timely manner to continue to maintain protective effects. This intelligent perceptual repair capability is not only the biggest feature of "Poly-Shield", but also a new technology with independent intellectual property rights.2017

june
, the process and Shandong grid officially started cooperation to develop self-healing coating additives and related products, the first to build a self-healing nano-microball additive ton production line with independent intellectual property rights, and truly realized the full chain transformation from source technology to engineering applications.
