Effect of oxygen functional group coverage of graphene oxide on interfacial thermal conductance in phase change materials

Puntos clave

• Interfacial thermal conductance improves with increased oxygen functional group coverage on graphene oxide, enhancing efficiency.
• A significant increase in thermal conductance was recorded, with a key metric observing increases of up to 35%.
• Assessment using novel graphene oxide materials identifies how functional groups affect heat transfer mechanisms.
• Findings may enable better designs for thermal management in energy systems, potentially optimizing phase change materials.
