Due to the advantages of light weight and high strength, high temperature resistant resin is widely used in the field of aerospace. At present, although the preparation of reinforcement materials such as carbon fiber has made great progress, the development of supporting resin is still relatively lagging behind, which has become the bottleneck restricting the improvement of composite properties. Since the commercialization of phenolic resin in 1909, high-temperature-resistant resin has developed for more than 100 years, from which many excellent resin systems have been born, and the service temperature has increased from the original 100 ℃ to the current mainstream 400 ℃. The current question is: can the service temperature of the resin be increased by a little, and can the speed of resin replacement be accelerated to meet the further needs of the aerospace field? In addition, from the perspective of processing, the curing temperature of the resin should be reduced as much as possible to improve the processing performance. However, the contradiction between improving the heat resistance and reducing the curing temperature is common in the design of thermosetting resin, just like you can't have your cake and eat it too, which brings great difficulties to the design of high-temperature-resistant resin.

Recently, Professor Jiaping Lin's group at East China University of Science and Technology has made a breakthrough in the design method of high-temperature-resistant-resin, established a material genome approach suitable for the design of high-performance polymers, greatly accelerated the research and development rate of resin, and expected to change the traditional material design method based on trial and error. The work was published in Chem.Mater. (DOI:/10.1021/acs.chemmater.0c00238)，an important journal in the field of material chemistry, under the title of Rational Design of Heat-Resistant Polymers with LowCuring Energies by a Materials Genome Approach. The developed material genome approach methods include gene definition, collection and combination, performance prediction, structure screening, performance verification and so on.

The work was completed by Junli Zhu, a doctoral student at East China University of Science and Technology, and Ming Chu, a master student, under the guidance of Associate Professor Liquan Wang. The research work has been guided by Professor Jiaping Lin and Professor Lei Du, a well-known expert in the field of high temperature resistant resins. With the goal of standing in the sky, it not only develops theoretical design methods, but also meets the needs of practical applications, and promotes the high-quality development of polymer material genome approach.
