Sucrose-based carbon foams with enhanced thermal conductivity

Carbon foams are novelty materials that have a wide range of applications such as radiators, thermal protection, and fire-resistant cores. The main carbon sources of carbon foams are sucrose, coal, coal tar pitch, and petroleum pitch, however the foams that use sucrose as their primary source have low thermal conductivity. This paper examined the thermal properties of carbon foams derived from sucrose but used graphite fillers to improve thermal conductivity. ...

In-situ synthesis and attachment of colloidal ZnO nanoparticles inside porous carbon structures 

This study investigates the properties of a material to be used as an energy storage medium that can use energy stored from the summer months, and then release it during the winter. The proposed material uses a graphite foam, with ZnO coatings with a flower like morphology, to house a sugar alcohol phase change material (PCM). The thermal conductivity of the material was measured using a transient plane source (TPS) ...

Biomass-derived, thermally conducting, carbon foams for seasonal thermal storage

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 thermal analyzer 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 ...

Ultralow cost reticulated carbon foams from household cleaning pad wastes

In this paper, cost efficient RVC foams were fabricated from household cleaning pad waste (CPW) and sucrose. A thermal analyzer measured the thermal conductivity of the RVC foams using the transient plane source (TPS) method. Results showed that the thermal conductivity of the CPW foams were significantly lower than Ultramet’s RVC foams which are highly insulative. This study proved that it is possible to reproduce low-cost carbon foams from ...

Closed-cell carbon foams from diphenolic acid-based polybenzoxazine

Carbon foams were prepared from diphenolic acid-based benzoxazine foams by pyrolysis under nitrogen atmosphere. The method used in this article produced foams containing a large fraction of closed cells which is uncommon for carbon foams. The foams studied were found to possess similar mechanical properties common to other carbon foams; however, the presence of the high fraction of closed cells led to the lowest observed thermal conductivity ever reported for ...
