Area of Science:

  • Materials Science
  • Chemical Engineering

Background:

  • Phase change materials (PCMs) are crucial for thermal energy storage.
  • Developing efficient and stable PCMs, particularly those based on expanded graphite and paraffin, remains an active research area.

Purpose of the Study:

  • To develop an efficient, sustainable, and low-temperature method for preparing expanded graphite/paraffin composite phase change materials (EG/PA-based PCMs).
  • To elucidate the preparation mechanism and characterize the properties of the synthesized PCMs.

Main Methods:

  • Low-temperature synchronous expansion-adsorption method.
  • Characterization techniques including FTIR, SEM, BET, XPS, XRD, TG-DSC, and VASP simulations.
  • Analysis of pore volume, weight loss, thermal conductivity, and interlayer spacing.

Main Results:

  • The EG:Paraffin = 1:4 sample demonstrated effective paraffin adsorption within the expanded graphite structure, leading to enhanced leak resistance and improved thermal conductivity (0.20 W/(m·K)).
  • Minimal pore volume and low total weight loss were observed for the EG:Paraffin = 1:4 sample, indicating optimal paraffin loading.
  • The process effectively increased the interlayer spacing of expanded graphite, resulting in a significant expansion volume (203 mL/g).
  • XPS spectra and simulation calculations confirmed a physical mixture between expanded graphite and paraffin.

Conclusions:

  • The study presents an innovative, greener, and energy-efficient method for synthesizing EG/PA-based composite PCMs.
  • The developed method facilitates controllable microstructure and supports large-scale production of these advanced PCMs for thermal energy storage.
