Beyond It’s good competition—Interview with Zhu Meifang, academician of the Chinese Academy of Sciences and dean of the School of Materials Science and Engineering at Donghua University
Zhu Meifang, academician of the Chinese Academy of Sciences and doctoral supervisor. Dean of the School of Materials Science and Engineering, Donghua University, and Director of the State Key Laboratory of Fiber Material Modification. Expert of the national “863” key special project on ‘nanomaterials’ in the field of new materials, director of the China Materials Society and China Textile Engineering Society, executive director of the Shanghai Composite Materials Society, “Journal of Polymers”, “Synthetic Fibers” and “Journal of Functional Polymers” 》 Editorial Board Member. Systematic research has been carried out in the field of fiber material science and engineering, especially in the functionalization and high performance of polypropylene fibers, new nanocomposites and special functional materials and their fiber-forming technologies (biomedical fibers, phase change materials), etc. He has conducted in-depth research, published more than 260 papers included in SCI, obtained more than 100 authorized Chinese invention patents, and won 11 national, provincial and ministerial level science and technology awards. He was selected into the National Outstanding Youth Fund, Cheung Kong Scholars Distinguished Professor, and the Innovation Team in Key Areas of the Ministry of Science and Technology’s Innovative Talent Promotion Plan. He was awarded the First National Innovation Certificate, the Ho Leung Ho Lee Foundation Youth Innovation Award, etc.
Smart fiber applications are still in the pre-commercial stage
“Big Fiber Briefing”: Hello, Academician Zhu, thank you for accepting the exclusive interview with “Big Fiber Briefing”. First of all, many people in the industry who are concerned about the development of large fibers would like to know from you what are the current domestic and international progress and trends of smart fibers?
Zhu Meifang: Okay. First of all, I would like to say that the direction of big fiber (big fiber) that the big fiber working group has been promoting over the years is still in the right direction. Although it is still unclear whether the term big fiber can be accepted and popular on a wider scale. judge. It is generally understood that the so-called large fibers are not traditional fibers, but fibers with super properties, high performance, greenness and other characteristics. At present, our Donghua Institute of Materials Science and many units at home and abroad have published many papers focusing on smart fibers, wearables, etc. However, there has been limited progress from laboratory research to industrialization, and most of them are still in the exploratory stage before practical application.
Only after research on the international trends in large fiber can we make some judgments. There are many international research papers and publications on smart fibers, which need to be studied and summarized. Dr. Wang Gang of our team just returned from studying at Northwestern University and Argonne Laboratory last year. According to his understanding, the team of Academician John Rogers of Northwestern University has integrated complex touch into AR/VR (artificial intelligence/virtual reality) for the first time. We know that touch is one of the most important senses of the human body, and it is the basis of our connection with the physical. Previously, how to integrate touch into VR/AR technology was a huge problem in this field. The main difficulty came from how to encode the stimulation detected by the sensory receptors into information that the computer can perceive and understand. This process is very complicated. The research team developed a wireless, battery-free haptic actuator. Its electronic system platform enables the tactile interface to be gently laminated on the curved surface of the skin, transmitting information through spatiotemporally programmable local mechanical vibration patterns, thereby achieving Complex touch sense is integrated into VR/AR technology.
In terms of bionic materials, researchers from Seoul National University in South Korea have prepared ionic spider webs, which simulate sensing and cleaning capabilities through bionic electrostatic theory. According to reports, this method can be applied to all electrostatic-based robotic components, such as actuated exoskeletons and capacitive tactile sensors. Although this bionic material is still in the research stage, it is a breakthrough in the original bionic concept anyway.
Preparing to establish the “International Alliance for Digital Health and Intelligent Materials”
“Big Fiber Briefing”: The School of Materials Science and Technology of Donghua University has always been in a phalanx position in the field of polymer fiber materials at home and abroad. Although it is during the holiday, I entered the school from the school gate and saw many students walking in a hurry. , many people in the laboratory building were coming in and out, it felt very busy. Please introduce Dean Zhu to some of the work our college has done since the epidemic.
Zhu Meifang: The epidemic actually has no impact on our work. In the first half of this year, we did more than ever before (of course, there were a lot less business trips). Many people in our team and the State Key Laboratory…
