Abstract:

The structure of polymer products has obvious multi-level and polydispersity. The performance is also very rich. In this article, it was suggested that the rational design based on quantitative relationship between structure and performance and the precise manufacturing of product structures should be taken as the core research content and innovative development approach of the polymer product engineering. In order to accurately describe the relationship between polymer structure and performance, the database construction of polymer and polymer informatics derived therefrom, especially the application of artificial intelligence technology, should be paid more attention in the future. For more precise manufacturing of polymer structures, in the future, attention should be paid to the CNC manufacturing of molecules in the polymerization process. At the same time, the soft measurement technology for polymerization process should be continuously innovated and developed to improve the scope, accuracy and speed of the online detection of structure during the manufacturing process of polymer products. The article also pointed out that attention should be paid to the in-situ alloying and compounding methods of polymers in the reactor and the application research of reactive extrusion on molecular modification, group conversion, chain extension, cross-linking, alloying and compounding of polymers, so as to fully leverage their advantages in the precise manufacturing of multiphase and multi-component polymer products.
