Abstract: With the advances of advanced materials and increasing consumption of energy, people are pursuing structural-integrated composites to make multifunction’s within one unit. With any dimension in any phase less than 100 nm, nanocomposites are defined as two or more materials with different properties that remain separate and distinct on a macroscopic level within one unity. Nanocomposites have demonstrated unique physicochemical properties and wide applications. Two challenges exist facing the manufacturing and applications of nanocomposites, i.e., agglomeration and particle-matrix infections. To obtain uniformly dispersed nanofillers and strong particle-matrix interaction is important for their improved properties especially the mechanical properties. In this talk, the ways to prepare the nanocomposites with different matrices (such as polymer, carbon and ceramic matrix), their unique properties and their applications will be presented. The applications will include electromagnetic interference (EMI) shielding, sensing (strain and magnetic field) and energy conversion/storage units such as electrochemical capacitors.
Bio: Dr. Guo, currently an associate professor in the Chemical & Biomolecular Engineering Department of at the University of Tennessee Knoxville (UTK), obtained his bachelor’s degree from Shan-dong University of Science and Technology (1996), master’s degree from Beijing University of Chemical Technology (1999), and a Ph.D. degree from Louisiana State University (2005). All the degrees were from Chemical Engineering. Before joining UTK, Dr. Guo was working at Lamar University from 2008-2014 as an Assistant/Associate Professor in the Dan F. Smith Department of Chemical Engineering. Meanwhile, Dr. Guo had received a three-year (2005-2008) postdoctoral training in the Mechanical and Aerospace Engineering Department at the University of California Los Angeles. Dr. Guo directs the Integrated Composites Laboratory (ICL) with more than 20 members and has authored/co-authored more than 800 peer-reviewed journal papers and five patents with a total citation of over 48,000 and an h-index of more than 120. Dr. Guo had served as Chair for the Composites Division of AIChE (2011-2012). Dr. Guo is a lifetime fellow of the Indian Chemical Society. Dr. Guo’s current research team focuses on multifunctional light-weight nanocomposites, especially with polymer and carbon as the hosting matrix to solve the energy and sustainability issues. The research activities are currently supported by NSF, the American Chemical Society (ACS) Petroleum Research Fund (PRF), and several global industrial companies.
