Professor Xiangwu Zhang is currently the Associate Department Head and Director of Graduate Programs in the Department of Textile Engineering, Chemistry, and Science at North Carolina State University. Zhang's research interests focus on nanostructured and multifunctional polymer, composite, fiber, and textile materials with an emphasis on practical applications: i) energy storage and conversion, ii) chemical and biological protection, and iii) composites.His research encompasses both fundamental materials studies such as synthesis and physical characterization, as well as system design and fabrication. Zhang has received over five million dollars of research funding from the US government, foundation, and industry. Zhang has published two books, five book chapters, and more than 150 peer-reviewed journal articles. Zhang has also delivered over 200 presentations in international and national conferences. Recently, Zhang received the Alumni Association Outstanding Research Award and Outstanding Teacher Award.

报告摘要 :

Nanofibers are an important class of material that is useful in a variety of applications, including filtration, tissue engineering, protective clothing, battery separators, energy storage, etc. So far, electrospinning is the most used method for producing nanofibers. However, the wide-spread commercial use of electrospinning is limited due to its low production rate, poor safety, and high cost. Most other nanofiber production methods, such as melt-blowing, bicomponent fiber spinning, phase separation, template synthesis, and self-assembly, are complex and can only be used to make nanofibers from limited types of polymers. Centrifugal spinning is an alternative method for producing nanofibers from various materials. It has been demonstrated that the simple centrifugal spinning method is low cost and is two orders of magnitude faster than conventional electrospinning process. This presentation addresses the use of centrifugal spinning to produce advanced functional nanofibers for energy storage.
