On the afternoon of October 13, 2021, Professor Dong Jianhua was invited by Professor Huang Hui from the School of Materials Science and Optoelectronic Technology to give a lecture on "Overview of Polymer Chemistry and Materials" at Jiao 1-114.

      Macromolecular compounds are macromolecular substances. Polymer compounds are used as materials in various fields of people's production and life, and people's clothing, food, housing and transportation are inseparable from polymer materials. Many aspects of industrial and agricultural production, medical health, information technology, aerospace, and national defense industries are fields where polymer materials play an irreplaceable role, and new demands are constantly put forward for polymer materials. This report provides an overview of the basic knowledge of polymers, the research frontiers of polymer chemistry and materials, etc. Professor Dong first briefly introduced the 100-year development history of polymers, during which new materials with an annual output of 400 million tons were formed. Among them, general polymer materials such as polyolefins dominated, but there was still room for improvement in performance. Then he proposed emerging optoelectronics, biological Medical functional polymers have broad prospects, and environment-friendly, biodegradable polymer materials still need to be developed. The atmosphere of the lecture was good, and the exchanges and discussions between professors and students were active and enthusiastic.

      Dong Jianhua, male, graduated from the Department of Chemistry of Zhejiang University in 1982 with a bachelor's degree, and obtained a Ph.D. After two years of postdoctoral research in the Department of Chemistry of Peking University, he stayed on to teach until 1997. From 1998 to 2019, he was in charge of project management in the field of organic polymers at the National Natural Science Foundation of China (retired in June 2019). He has been a researcher since 1999, and has successively served as the director of various science fund projects, director of the science department, and second-level researcher in the fields of organic polymer materials, polymer science, materials chemistry and energy chemistry. He has organized many seminars on the development of disciplines and frontier strategies in the field of organic polymers, as well as major research projects and academic activities in operation and management. Editor-in-chief of three monographs on the frontiers, progress and prospects of the discipline; wrote chapters for related monographs many times.

       He served as the twenty-sixth director of the Chinese Chemical Society, the executive director of the twenty-eighth and twenty-ninth councils, and served as the deputy director of the Polymer Science Committee for a long time. Deputy Editor-in-Chief of the editorial committee of the polymer field of the third edition of "Encyclopedia of China", and has organized and written scientific dictionaries and disciplinary strategy reports for many times. From 2007 to present, Wiley Publishing Company's international academic journals "Advanced Technology Polymers" "Polymers for Advanced Technologies" Associate Editor (Associate Editors) 2011 to present "Royal Society of Chemistry Polymer Chemistry Series" editorial board member. He is on the editorial board of domestic academic journals such as Polymer Bulletin, Journal of Materials Research, Materials Herald, and Polymer Materials Science and Engineering.
