Abstract: Seasonal thermal storage based on phase change materials (PCMs) require a thermally conductive host because they typically have low thermal conductivities. In this study, tannin-based composite carbon foams were prepared using thermally conductive exfoliated graphite (EG) fillers and pMDI additives. A Hot Disk TPS 2500 S measured the thermal conductivity of the samples using the transient plane source (TPS) method. Results showed that the EG-carbon foams and the EG/pDMI-carbon foams showed significantly higher thermal conductivities than the pristine carbon foams. The success of this experiment indicates that EG- and pDMI-composite carbon foams have the potential to host PCMs for seasonal thermal storage applications.
