关于举行美国凯斯西储大学教授Lei Zhu讲座的通知
2020-04-13


讲座主题:高分子介电材料和应用(第三讲)


主讲人:Prof. Lei Zhu (美国凯斯西储大学)


时间:4月20日(周一)8:00-9:40 (Zoom线上讲座)


讲座概要:


High dielectric constant and low dielectric loss are desirable electrical properties for next generation polymer dielectrics that show promise for applications in pulsed power, power electronics, and printable electronics. Unfortunately, the dielectric constant of polymers is often limited to 2-5, much lower than that of inorganic dielectrics, because of the nature of hydrocarbon covalent bonds for electronic and atomic polarizations. It is essential to understand the fundamental physics of different types of polarization and the associated loss mechanisms in polymers. In this presentation, we discuss the characteristics of each polarization and explain how to enhance the polarization using rational material designs without causing significant dielectric losses. At last, we will introduce other dielectric applications for polymers such as nonwoven fabric electrets for N95 facial masks and respirators.


附嘉宾简介:



  Professor Lei Zhu received his B.S. degree in Materials Chemistry in 1993 and M.S. degree in Polymer Chemistry and Physics in 1996 from Fudan University.  He received his Ph.D. degree in Polymer Science from University of Akron in 2000. After two-year post-doctoral experience at the Maurice Morton Institute, University of Akron, he joint Institute of Materials Science and Department of Chemical, Materials and Biomolecular Engineering at University of Connecticut, as an assistant professor.  In 2007, he was promoted to associate professor with tenure.  In 2009, he moved to Department of Macromolecular Science and Engineering at Case Western Reserve University as an Associate Professor.  In 2013, he was promoted to full Professor.  His research interests include high κ polymer and organic-inorganic hybrid nanomaterials for high energy density capacitor applications, development of artificial antibody as nanomedicines, and supramolecular self-assembly of discotic liquid crystals.  He is recipient of NSF Career Award, 3M Non-tenured Faculty Award, DuPont Young Professor Award, and Rogers Teaching Excellence Award.  He is author and co-author of 190 refereed journal publications and 7 book chapters.  He delivered over 170 invited talks and 45 contributed presentations, and his total citation is ~9400 times with an h-index of 54 (Google Scholar).
