第17讲:中科院苏州纳米所李清文研究员——Assembling carbon nanotubes into functional composites and devices(2017.3.2)

How to assemble carbon nanotubes (CNT) in effective and productive ways is of vital importance for their applications. Recent progresses in CNT growth have inspired some new strategies and methods for the best utilization of the unique physiochemical properties of CNTs in macroscale materials and devices. Processing CNTs in a dry state, i.e. direct collecting CNT freestanding structures in air with sequent pressing, stretching and multilayer stacking instead of dispersing in solutions provides a route of assembling nanotubes that not only simplifies the processes considerably but also avoids structure damages of CNTs such as scission of nanotubes, sp2 bond breakage, and dispersant contamination. This talk provides an overview of various dry-procesable CNTs with a focus on preparation methods and the properties of their macroscopic materials, including the following aspects: 1)The preparation techniques for nanotube aggregative morphologies and microstructure control; 2) Application of dry-processable CNTs for functional film devices; 3) Dry-processing of CNTs into strong CNT films and composites; 4) Opportunities and challenges for dry-processable methods.

报告人简介

Qingwen Li is a professor and deputy director of Suzhou institute of Nanotech and Nanobionic (SINANO), Chinese Academy of Science. She received her B.S. degree in chemistry from Xinjiang University in 1987, M.S. degree in Physical Chemistry from Shandong university in 1990 and Ph.D degree in physical chemistry from Tsinghua University in 2000. After her postdoc. research with prof. Zhongfan Liu at Peking university (2001-2003) and prof. Alan Windle at University of Cambridge (2003-2005), she joined in Los Alamos National Laboratory as an associate researcher (2005-2008) and SINANO as a hundred talented professor (2008-present). Her research interests focus on rational preparation and industrialization of nanocarbon materials for multifunctional composites and thin-film devices.
