In this study, the influence of adding MWCNTs to an alkyd-urethane coating has been studied on the thermal conductivity coefficient K of the coating, to determine its potential for use in solar water heating applications where the low value of the thermal conductivity coefficient of the polymeric coatings is an obstacle to their use as absorbent surfaces in solar collectors. A light source, a halogen lamp, was used as a heat source; the temperature measurement was done using an infrared thermometer. The results showed an enhancement in the thermal conductivity coefficient of 9.16% when it is added 4 % of the MWCNTs.
