Thermal properties enhancement of Hexadecan-1-ol with the addition of functionalized MWCNT
Hamza Ayaz, Eui Kim and Honghyun Cho
The potential PCMs show good thermal properties which makes them a good choice but the low thermal conductivity limits their application. In this study, PCM nanocomposites are prepared with the inclusion of MWCNT and investigated the thermal and chemical stability. As a result, the stability of the prepared PCM with nanoparticles shows no agglomeration during 48 hours by visual inspection. In addition, the Hexadecan-1-ol which is chosen as base PCM has a phase change temperature of 45°C with 230 J/g latent heat of fusion. The thermal conductivity of the base PCM was 0.309 W/m·K, and it was a 68% enhancement of the thermal conductivity compared to that of the 4wt% nano-enhanced PCM (NEPCM). The prepared NEPCM can be utilized for various thermal applications like hot water tanks, thermal management of Li-ion battery modules, and domestic floor heating.
