  • Abstract
  • I will discuss our recent progress on engineering of 2D materials, with a focus on metal ion intercalation and ultra-high temperature treatment (up to 3000-3500K). We developed a nano-battery platform that allows in situ measurement of optical, electrical and structure changes of 2D materials during ion intercalations. We used the nano-battery setup to investigate various properties of 2D materials upon ion intercalation, including Li+, Na+ and K+. Dramatic increases in both transmittance and conductivity were reported, which leads to the highest figure of merit (FOM) for transparent conductor applications. We also extended the knowledge to printed reduced graphene oxide network toward large-scale applications. In a separated topic, I will discuss our effort in the past two years on high temperature material behavior for reduced graphene oxide (RGO) networks. High-temperature stability of RGO networks allows us to uniquely engineer them for a range of emerging applications, such as 3D printed rapid heaters and highly conductive RGO paper as lightweight battery current collectors.
  • Biography
  • Liangbing Hu received his B.S. in physics from the University of Science and Technology of China (USTC) in 2002, where he worked with Prof Yuheng Zhang on colossal magnetoresistance (CMR) materials for three years. He did his Ph.D. in at UCLA (with George Gruner), focusing on carbon nanotube based nanoelectronics (2002-2007). In 2006, he joined Unidym Inc ( as a co-founding scientist. At Unidym, Liangbing’s role was the development of roll-to-roll printed carbon nanotube transparent electrodes and device integrations into touch screens, LCDs, flexible OLEDs and solar cells. He worked at Stanford University (with Yi Cui) from 2009-2011, where he work on various energy devices based on nanomaterials and nanostructures. Currently, he is an Associate Professor at University of Maryland College Park. His research interests include nanomaterials and nanostructures, roll-to-roll nanomanufacturing, energy storage focusing on solid-state batteries and Na ion batteries, and printed electronics. He received many awards, including: Office of Naval Research Young Investigator Award (2016), ACS Division of Energy and Fuel Emerging Investigator Award (2016), SME Outstanding Young Manufacturing Engineer Award (2016), University of Maryland Junior Faculty Award (School of Engineering, 2015), 3M Non-tenured Faculty Award (2015), Maryland Outstanding Young Engineer (2014), University of Maryland Invention of Year (2013 Physical Science), Campus Star of the American Society for Engineering Education (2014), Air Force Young Investigator Award (AFOSR YIP, 2013).
