The Influence of Carbon Fillers on Thermal Transport in Polyurethane

Article Preview

Abstract:

The paper is devoted to the study of thermal, as well as mechanical properties of polyurethane samples (PU) filled by carbon black (CB), graphite (G) and MWCNT(CNT). Thermal conductivity k(W.m^-1.K^-1), specific heat capacity c_p(J.kg^-1.K^-1) and thermal diffusivity a(mm².s^-1) were measured by the impulse method. An increase of all the above mentioned thermal parameters after addition of fillers under investigation was observed. The dc electrical conductivity drastically increases from PUPU+CBPU+GPU+CNT.
