Abstract

In this work, we investigated the possibility of applying polyurethane in thermoelectric application, and the influence of MWNT concentrations to polyurethane / multiwalled carbon nanotube composites on the thermoelectric performance. The composites were prepared by solution blending method. Different MWNT concentrations from 5% to 60% were added into the polyurethane matrix. The electrical conductivity, Seebeck coefficient and thermal conductivity of the prepared composites were measured. The electrical conductivity was increased with the addition of more MWNTs. The Seebeck coefficient decreased slightly with the increase of the MWNT loading. The thermal conductivities increased with the addition of more MWNTs. A reasonable Seebeck coefficient of ∼33μV/K suggested that polyurethane can be used in thermoelectric application. These flexible and stretchable composite films could be used for some special applications where flexibility and stretchability are needed.
