| description | PCMs low thermal conductivity and leakage problem hindered their widespread use in TES applications. In the
present research, a newly synthesized porous structured 3-D expanded graphite (EG) additive is used to improve
low thermal conductivity and provide shape stability to a PCM. Herein, EG particles were synthesized using
expandable graphite with the help of a tube furnace at 900 ◦C for 35 min. Further, shape-stable phase change
materials (SS-PCMs) were developed by infusing EG particles into liquid A70 (PCM) using the vacuum
impregnation method. The experimental results revealed that EG particles improved the low thermal conductivity
and reduced the leakage problem of PCMs. The newly developed SS-PCMs demonstrate an outstanding
thermal conductivity of 1.59 W/(m⋅K), increased by 657.16 % compared to base (A70) PCM. Additionally, 500
thermal cycles were carried out on the SS-PCM composites. The composite showed a minimum change in the
thermophysical properties based on the results. Moreover, an electro-thermal energy conversion experiment was
conducted to analyze the developed SS-PCM thermal energy efficiency, and the SS-PCM composite achieves a
transformation capability of 70.89 % when operated at 4.8 V. In conclusion, superior thermal conductivity is
shown by newly developed SS-PCMs with 3D expanded graphite, which are perfect for ensuring efficient thermal
management in electronic devices and energy storage systems. |
