From November 3 to November 6, 2021, the "Development and Application of Anti-bacterial and Anti-epidemic New Materials" senior seminar sponsored by Shanghai Municipal Human Resources and Social Security Bureau, Shanghai Municipal Economic and Information Commission as the guiding unit, Shanghai New Materials Talent Training Base and Shanghai New Materials Association/Anti-bacterial and Anti-epidemic New Materials Professional Committee was successfully held in the Central International Hotel, Putuo District, Shanghai.

This senior seminar brought together a number of experts and scholars in the field of antibacterial and epidemic prevention, from different perspectives such as materials, testing, product development, etc., to bring a feast of antibacterial and antiviral related materials expertise for the registered students.

Different from the previous internal exchanges of the industry, the invited experts and scholars specially prepared the corresponding textbooks and handouts, from the past 20 minutes of general talk, extended to one and a half hours, even two hours of in-depth discussion, can be described as full of sincerity. Participants from all walks of life across the country, even teachers from universities and colleges, in order to understand the latest knowledge in the field of antibacterial and epidemic prevention, also came to learn. At the moment when the epidemic is still severe, it is difficult to hold such a learning class, and the students are very interested in knowledge.

Mr. He Koubao, Secretary-General of Shanghai New Materials Association, and Dr. Ma Zhengsheng, director of the Special Committee on Antimicrobial and Epidemic Prevention, respectively delivered speeches at the opening ceremony.

The participants were generally very interested in the lecturers' content, and the 10 to 20 minutes of communication and discussion time set aside at the end of the course was still not enough.

After the end of the senior research class, the Secretary General He and Director Ma of the special committeel issued training certificates to the students.

The successful holding of the advanced research class not only popularized the professional knowledge related to antibacterial and epidemic prevention materials, but also strengthened the interaction between the participants.

In the current situation of epidemic prevention and control is still grim, the holding of this high-level research class will be of great benefit to all participating units to exchange information, promote each other, and jointly develop products that meet the needs of epidemic prevention!
