Polyamide (PA, commonly known as nylon) has the advantages of good mechanical properties, heat resistance, chemical resistance, abrasion resistance and self-lubricating properties, and easy processing. The products are widely used in automobile, aviation, aerospace, shipbuilding, Electrical and Electronics, Information, Power Tools, Textiles and other fields. At present, the total consumption of polyamide in the world has exceeded 6 million tons, of which polyamide engineering plastics has reached more than 4 million tons, making it the most widely used and most widely used polymer material in the engineering plastics industry. Engineering plastics are an important part of polymer materials and belong to the strategic emerging industries that are mainly cultivated by the state. Polyamide engineering plastics have been listed in the topic of "Basic Materials" of the "Medium and Long-Term Scientific and Technological Development Plan for the Nation (2006-2020) .
During the "12th Five-Year Plan" period, the Ministry of Science and Technology implemented the project of "National Science and Technology Supporting Plan for the Development and Industrialization of Key Technology for High Performance Polyamide Engineering Plastics Preparation". The performance indexes of the completed technical products reached the same category The advanced level of products. The main products have been applied in the field of electronic appliances, automobiles and other fields to fill the gaps in the research field of high-end polyamide engineering plastics in our country and realized industrialization. It has promoted the development and application of high-performance polyamide engineering plastics in our country, promoted the development of polymer materials industry in our country, provided technical support for industrial upgrading, especially adjusted the product structure for engineering plastic industry and reduced the processing energy consumption And enhance the level of development of national strategic industries have a positive meaning.
In order to promote scientific and technological innovation and industrialization in the field of materials in China, the Ministry of Science and Technology has formulated the "Special Plan for Science and Technology Innovation in the Thirteenth Five-Year Plan" in the field of materials and clearly put forward the key technologies for the development of advanced structural materials such as special engineering plastics and marine engineering materials; Materials, smart / biomimetic / metamaterials, high temperature superconducting materials, new biomedical materials, eco-environmental materials and other special functions and smart materials technology; new microelectronics / optoelectronics / magnetoelectronic materials, printed electronic materials, functional crystals and laser technology Strategic advanced electronic materials technology; high-throughput design / preparation / characterization of the material genome technology; graphene and other nano-materials technology. Promote the formation of strategic emerging industries growth point, and effectively promote the development of the material industry with broad market prospects, low resource consumption, high coefficient of motivation, more employment opportunities and comprehensive benefits.
