On the afternoon of 8 November 2023, Professor Dong Jianhua was invited by Professor Huang Hui of the School of Materials Science and Optoelectronics Technology to give a lecture on "Polymer Chemistry and Materials Overview" in Teaching 1-417.

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. This report summarizes the basic knowledge of polymers, the research frontiers of polymer chemistry and materials, etc. Professor Dong first briefly introduced what is polymer material, the difference between polymer and small molecule, and introduced various natural polymer materials, synthetic polymer materials and so on. Then the development history of polymer industry in China and the history of polymer chemistry are introduced. Then the application of polymer in food, clothing, housing and transportation is introduced, especially the application of polymer materials in medicine is introduced. Polymer recycling has always been the focus of attention in the industry. Professor Dong introduced the current situation and existing problems of polymer recycling in detail. In addition, Professor Dong also introduced the cutting-edge applications of polymers, including biochemistry and temperature sensors, molecular electronics devices, displays, light-emitting diodes, and field effect transistors. At last, Professor Dong and the on-site teachers and students conducted exchanges and discussions, and got a warm response from the on-site teachers and students.

Dong Jianhua, male, received his bachelor's degree in Chemistry from Zhejiang University in 1982 and his Doctor of Science degree from the Institute of Chemistry, Chinese Academy of Sciences in 1989. After two years of postdoctoral research in the Department of Chemistry, Peking University, he continued to teach there until December 1997. From 1998 to 2019, he was responsible for project management in the field of organic polymers at the National Natural Science Foundation of China (retired in June 2019). Since 1999, he has been a researcher, and has successively served as the director of various scientific fund projects, the director of Scientific Division, and the second-level researcher in the fields of organic polymer materials, polymer science, materials chemistry and energy chemistry. We have organized many research seminars on the development and frontier strategies of organic polymers, as well as academic activities on the establishment and operation of major research projects. Edited three monographs on the frontiers, progress and prospects of this discipline; He has written several chapters for related monographs.

He was a member of the 26th Council of the Chinese Chemical Society, the executive director of the 28th and 29th Council, and the deputy director of the polymer Science Committee for a long time. Deputy editor of the polymer editorial Board of Chemistry Volume of the Third edition of the Encyclopedia of China, he has organized and written scientific dictionaries and disciplinary strategy reports for many times. 2007-present Wiley Publishing Company international academic professional journal "Polymers for Advanced Technologies" "Associate editor" Editors, 2011 - Member of the Editorial Board of the Royal Society of Chemistry Series on Polymer Chemistry. He has served as editorial board member of many domestic academic journals. He studied in universities in the United States and Korea for two and a half years.
