专家介绍： Dr. Qingwen Li is now a professor and vice director of Suzhou Institute of Nano-Tech and Nano-Bionic, Chinese Academy of Sciences. She got her B.S. and M.S. in physical chemistry in1987 and 1990 from Xinjiang University and Shandong University, respectively. She obtained her PhD in science from Tsinghua University in 2000. From 2001 to 2008, she has worked as postdoc. research associate in Peking university, University of Cambridge and Los Alamos national laboratory. Her research experience focused on the synthesis and processing of carbon nanotubes for strong and multifunctional fibers. Due to her achievements on carbon nanotubes, she won the Nano 50TM and Micro 25 awards in 2007 (USA) and also the award of excellence by Los Alamos National lab. She joined in Suzhou institute of Nano-Tech and Nano-Bionics at the end of 2007 as a professor of “hundred talent project” supported by Chinese Academy of Science. Her current research focus on: 1) continuous growth of carbon nanotubes into multifunctional macroasseblies; 2) Selective sorting of single-walled carbon nanotubes for thin film devices; 3) application of sp2 nanocarbon and low-dimensional nanomaterials for functional composites and energy devices. She has published over 280 peer reviewed journal articles and applied more than 50 Chinese patents.
摘要: Carbon nanotube fibers (CNTs) are considered as one of the super fibers that boost many important applications, due to their light weight, high strength, high conductivity, and high stability. In this report, I will introduce the work done by our research group in recent years on mechanical enhancement, functional exploration and the application of carbon nanotube fibers. In the field of carbon nanotube fiber reinforcement, I will mainly introduce our progress made in the preparation of composite fibers, mechanical enhancement, transient covalent bonding of carbon nanotubes, and mechanical properties at extreme environmental conditions of carbon nanotube fibers. In the functional exploration and application of carbon nanotube fibers, we will mainly introduce the preparation of metal-coated carbon nanotube fibers for light-weight conductive wires, high current-carrying fibers, environmentally responsive artificial muscle fibers, and fiber energy conversion devices.
