Characterization of exfoliated graphite nanoplatelets

Exfoliated graphite nanoplatelets (GNP) can be added polymers to produce electrically conductive composites. In this study, varying amounts (2–15 wt%) GNP were added to polycarbonate (PC) and the resulting composites were tested for electrical conductivity (1/electrical resistivity), thermal conductivity, and tensile, flexural, and rheological properties.

A review of exfoliated graphite SpringerLink

26/07/2015· Exfoliated graphite (EG) refers to graphite that has a degree of separation of a substantial portion of the carbon layers in the graphite. Graphite nanoplatelet (GNP) is commonly prepared by mechanical agitation of EG. The EG exhibits clinginess, due to its cellular structure, but GNP does not. The clinginess allows the formation of EG compacts and flexible graphite sheet without a binder.

Thermal Performance Evaluation of Fatty Acid Ester and

Exfoliated graphite nanoplatelets (xGnP) which are porous and nano-sized carbon materials are suitable [14–18]. Additionally, they have a layered structure and are very cost effective. The low coefficient of thermal expansion of xGnP, is a desirable property for composite structural applications [19–22]. In this research, we prepared Mixed SSPCMs by impregnating two types of PCMs, coconut
