Thermal Conductivity and Thermal Boundary Conductance Measurements of Metal/PEDOT:PSS Interfaces as a Function of Electrical Conductivity


Principal Investigator:


PI: Dr. Costel Constantin, Department of Physics and Astronomy, JMU

Co-PI: Dr. Patrick Hopkins, Department of Mechanical and Aerospace Engineering, UVA


This project seeks to explore and reveal the thermal conductivity and thermal boundary conductance (i.e., Kapitza conductance) of PERDOT:PSS [i.e., poly(3,4-ethylenedioxythipohene) poly(styrenesulfonate)] as a function of electrical conductivity. PEDOT together with PSS form a macromolecular salt with electrical conductivity capabilities. This combined with good thermal stability at high temperatures, makes PEDOT:PSS an important material that can be used for future flexible devices including solar cells, transistors, and touch panel screens.
