The key project of the Chinese Academy of Sciences, "Research on Key Materials for Strategic Emerging Industries", passed the expert acceptance

Recently, the key project of the Chinese Academy of Sciences "Research on Key Materials for Strategic Emerging Industries" passed the expert acceptance organized by the Major Scientific and Technological Mission Bureau of the Chinese Academy of Sciences in Changchun.

It is reported that in 2012, the Chinese Academy of Sciences launched the key deployment project of "Research on Key Materials for Strategic Emerging Industries", focusing on the research work on four topics: "Preparation and application research of polymer materials based on transition metal catalysis", "Key nuclear primary structure and functional materials", "Research on important artificial tissue materials", and "Key materials and process technologies for photoelectric conversion and storage and their system integration".

The project is led by the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, and co-undertaken by the Shanghai Institute of Organic Chemistry, the Institute of Metal Research, and others.

After more than five years of unremitting efforts, the researchers of this project have developed a new generation of fully synthetic base oil, carbon dioxide-based polymer polyols, I-690 alloy pipes and nickel-based welding materials, as well as nuclear lubricating materials, a new generation of bilirubin adsorption materials, composite calcium silicate ceramic coating materials on the surface of bone implants, and key materials for dye-sensitized batteries. The research results have made breakthroughs in the preparation technology of a new generation of fully synthetic base oils and carbon dioxide-based polymer polyols; ultra-pure smelting of I-690 alloys and homogenization of pipe tissue, drawing and defect control of nickel-based welding materials, compounding and preparation technology of nuclear lubricating materials; preparation technology of a new generation of bilirubin adsorption materials, preparation technology of composite calcium silicate ceramic coating on the surface of bone implants; key materials technology for dye-sensitized batteries, high-stability electrolytes, instantaneous thermal curing packaging technology and other key technologies for new materials.

The project leader revealed that the project has completed the design of a thousand-ton/year high-performance polyethylene oil demonstration process package; built a thousand-ton test line for low-molecular-weight carbon dioxide-based polyols, and stably produced more than 300 tons of polyols; the developed I-690 alloy heat transfer tube has been applied; built a megawatt-level automated production line for dye-sensitized batteries, constructed an intelligent microgrid system including power generation, energy storage and energy-saving load modules, and trained a group of young and middle-aged backbone talents in the fields of polymer materials, nuclear materials, biomedical materials, photovoltaic power generation and energy storage materials.
