XiangwuZhang is a Professor and Alumni Distinguished Graduate Professor in theDepartment of Textile Engineering, Chemistry, and Science in the College ofTextiles at North Carolina State University. He currently serves as theAssociate Department Head and Director of Graduate Programs. Zhang earned aB.S. in Polymer Materials and Engineering in 1997 and a Ph.D. in MaterialsScience and Engineering in 2001, both from Zhejiang University, China. Zhang'sresearch interests focus on nanostructured and multifunctional polymer,composite, fiber, and textile materials with an emphasis on practicalapplications: i) energy storage and conversion, ii) chemical andbiological protection, and iii) composites. His research encompasses bothfundamental materials studies such as synthesis and physical characterization,as well as system design and fabrication. Zhang has received over seven milliondollars of research funding from the US government, foundation, and industry. Zhanghas published two books, seven book chapters, and more than 170 peer-reviewedjournal articles. Zhang has also delivered over 200 presentations ininternational and national conferences. Recently, Zhang received DistinguishedAchievement Award in Fiber Science (The Fiber Society, 2015), OutstandingService Award (Sigma XI Society - Scientific Research Society, 2015), InauguralUniversity Faculty Scholar Award (NC State, 2013), Alumni AssociationOutstanding Research Award (NC State, 2013), and Outstanding Teacher Award (NCState, 2013). Zhang is also a Yangguang Chair Professor at Wuhan TextileUniversity and a Guest Professor at Zhejiang Sci-Tec University.

讲座简介:

Nanofibers are an important class of material that isuseful in a variety of applications, including filtration, tissue engineering,protective clothing, composites, battery separators, energy storage, etc. Sofar, electrospinning is the most studied method for producing nanofibers. Aliterature search using the Web of ScienceTM database shows that Year 2015alone had publication of over 3000 articles in the electrospinning ofnanofibers. Among these publications, over 50% focused on the investigation ofthe electrospinning process and the characterization of the resultantnanofibers, and the others mainly address the innovative use of electrospunnanofibers for various applications. However, the wide-spread commercial use ofelectrospinning is limited due to its low production rate, poor safety, andhigh cost. Most other nanofiber production methods, such as phase separation,template synthesis, and self-assembly, are complex and can only be used to makenanofibers from limited types of materials. This presentation introduces asimple, yet versatile technique for producing nanofibers of various materialsincluding polymers, carbons, ceramics, metals, and composites. Centrifugalspinning eliminates the limitations encountered by current nanofiber productionmethods and can produce nanofibers at high speed and low cost.Centrifugally-spun nanofibers can be used invarious applications, including filtration, tissue engineering, protectiveclothing, composites, battery separators, energy storage, etc. The applicationof centrifugally-spun nanofibers in energy storage applications will bediscussed in this presentation.
