HEATER Seminar Series: Kefeng Cai, Tongji University

Research Progress in Polymer and Polymer Based Thermoelectric Materials

Research Progress in Polymer and Polymer Based Thermoelectric Materials

In this presentation, background related to thermoelectrics, including thermoelectric effects, thermoelectric conversion efficiency and applications of thermoelectric devices will be briefly introduced. Important research progress in the field of thermoelectrics, including new concepts, new material systems, with a focus on polymer and polymer based thermoelectrics during the last decade will follow. Finally, research progress in conducting polymers (e.g. PEDOT:Tos:PPP) and conducting polymer-inorganic nanostructure composites (including PANI/PbTe, PANI/Ag 2 Te, PEDOT/Ag(Cu), PEDOT/PbTe, PEDOT:PSS/Bi 2 Te 3 , PEDOT:PSS/graphene, and PPY/carbon nanotubes) will be described. Prof. Cai’s research group will also be introduced.


Prof. Kefeng CAI received his B.S. and Ph.D. from Wuhan University of Technology (PR China) in 1987 and 1998, respectively. He worked on Materials Synthesis and Processing at the State Key Laboratory of Advanced Technology, Wuhan University of Technology from 1987 to 2001 (as an associate professor since 1995). He was a Postdoctoral fellow from February 1999 to January 2001 at Physics Department, University of the Witwatersrand, South Africa, worked as an Alexander von Humboldt Research Fellow from August 2001 to December 2002 at Materials Research Institute, German Aerospace Center, and was a senior visiting scholar at CSIRO, Australia from July to August 2012. He joined Tongji University as a professor since 2003. He is interested in thermoelectrics and synthesis and characterization of nanomaterials. Currently he is a member of International thermoelectric society and senior member of American Nanosociety, and he is also an Editorial Board member of Global Journal of Physical Chemistry and World Journal of Nano Science and Engineering. He has published more than 80 research journal papers, two review papers and 10 patents.
