| Abstract Scope |
The development of efficient thermal energy storage materials is vital for advancing sustainable energy systems. Phase Change Materials (PCMs) store and release heat through phase transitions but suffer from low thermal conductivity, limiting their practical utility. This study addresses this challenge by integrating 2-dimensional (2D) nitrogen-doped graphene (N-G) into paraffin wax (m.p. 53–58 °C) to form a PCM composite with enhanced thermal properties. N-G was synthesized from graphene oxide and melamine via a ball milling process, introducing functional groups that promote molecular-level interactions with the PCM. The N-G/Paraffin integration was done using a controlled sonication method. Characterizations using DSC, FTIR, and XPS confirmed improved thermal behavior and structural integration. Notably, the 2 wt% N-G composite exhibited increased thermal conductivity and ~5% higher latent heat than pure paraffin, overcoming the longstanding trade-off between conductivity and storage capacity. These findings offer a viable route to high-performance PCMs via functional 2D nanoparticle integration. |
