Dr. Pengjian Gong, Associate Professor, doctoral supervisor, a member of the State Key Laboratory of Polymer Materials Engineering (SKLPME, Sichuan University). I received a bachelor degree from Shanghai Jiao Tong University (SJTU) in 2007, a master degree from East China University of Science and Technology (ECUST) in 2010, a doctorate degree from Kyoto University in Japan in 2013 (scholarship from the Ministry of Education, Culture, Sports, and Culture of Japan), and engaged in postdoctoral research at the University of Toronto (UofT), Canada from 2014 to 2016 (co-supervisor: Professor Chul B. Park, Foreign Academician of the Chinese Academy of Engineering), and joined the School of Polymer Science and Engineering (PSE) of Sichuan University (SCU) as an introduced talent in 2016. In 2018, I was awarded the Outstanding Young Talent of SKLPME. In 2020, I was awarded the Overseas High-level Talent of Sichuan Province. In 2021, I was awarded the National Petroleum and Chemical Education Outstanding Teaching Team Award. In 2024, I was awarded Sichuan Provincial Academic and Technical Leader Reserve Candidate.

As the project leader, I has presided over more than 10 projects such as the National Natural Science Foundation of China (general, youth, and key project sub-projects), international cooperation of the Provincial Department of Science and Technology, and school-enterprise cooperation, and participated in a number of key/major projects of the National Natural Science Foundation of China as a key R&D personnel, such as national defense and military industry, and major school-enterprise cooperation; Undertake undergraduate/master's teaching work such as "Polymer Physics" and "Material Characterization Methods"; In Journals in the field of materials and engineering, such as Carbon, Green Chem, Compos. Part A Appl. Sci. Manuf., Prog. Org. Coat., Polymer, Ind. Eng. Chem. Res. et al. I have published more than 40 papers. As the first inventor, I have applied more than 30 invention patents (including more than 10 authorized).

After returning to China in 2016, I have been committed to the research on the structural properties of porous materials and the industrial application and development of electromagnetic signal transmitting materials, adopting a new green and environmentally friendly supercritical fluid foaming method, combining numerical simulation to design the material structure, and developing new high-performance and multi-functional foaming materials, especially in next-generation communication, effectively improving the efficiency of a new generation of millimeter wave communication. Based on the existing R&D achievements, I have jointly carried out a number of industrialization development of information communication and green manufacturing with Huawei, Dow, Sinopec, JITRI and other enterprises, and independently designed and put into operation a 5G high-throughput transmission new material production line for relay antennas, satellite antennas, 5G base stations, etc.

In order to implement the country's strategic deployment of "accelerating the expansion of a new generation of information technology and other industries", and the corresponding "Made in China 2025" proposed by the green transformation and upgrading of the manufacturing industry, we use polymer materials as the base material and use the new supercritical fluid foaming processing technology to create a new type of high-throughput electromagnetic signal-transmitting material that meets the needs of the new generation of information technology. Research in related fields is being promoted from the following three aspects:

(1) 5G communication materials (new material structure design). A large amount of air is introduced into the material to promote the processing and preparation of new millimeter-wave high-throughput transmission materials prepared by supercritical fluid foaming, help the development of new 5G infrastructure, and give full play to the advantages of high electromagnetic signal transmission performance of polymer microporous materials in the direction of new generation information and communication construction.

(2) Basic theory (experimental and numerical simulation). Engineering application of high-performance porous functional materials (electromagnetic wave transmission, heat insulation, electromagnetic shielding, electrical conductivity, lightweight), theoretical research on energy conduction of porous media (thermal energy, electromagnetic energy), processing of polymer nanocomposites (graphene, carbon nanotubes), technology and theory of microcellular foaming (cell nucleation, cell growth);

(3) International Cooperation (CIAMP). We have worked closely with Professor Park, a Foreign Academician of the Chinese Academy of Engineering, to apply the successful experience of his Lightweight Materials Industry Application Center (CIAMP) in North America to the domestic foaming industry and promote the upgrading of green supercritical fluid foaming in China.
