Kerosene graphene nanoplatelets (GNP) nanofluids have a potential use in regenerative cooling of semi-cryogenic rocket thrust chamber. Before they can be used, more must be known about this substance's physical qualities. This study focuses on finding the effective thermal conductivity of this type of nanofluid, specifically at .005, 0.05 and 0.2 weight percentage (wt%) and 300, 500 and 750 mm2/g, specific surface area (SSA) of GNP. ...
Chemically modified graphene (CMG) was obtained by combining aminopropyllsobutyl polyhedral oligomeric silsesquioxane (NH2-POSS) and hydrazine monohydrate to functionalize graphene oxide (GO). CMG and polyimide (PI) were combined to create the CMG/PI nanocomposite. The properties of this nanocomposite were obtained using a variety of methods. The thermal conductivity measurements were performed using a TPS instrument by utilizing the transient plane source (TPS) method. It was found that the thermal ...
This article examined the properties of bismuth telluride (Bi2Te3) after “graphene-inspired” exfoliation left its crystalline films with a thickness of a few atoms. The thermal conductivities were found using the transient plane source (TPS) technique and the laser-flash method. An instrument was used for obtaining the thermal conductivity with the TPS technique. It was found that the exfoliated thin films have low thermal conductivity, relatively ...
In this study, graphene nanoplatelets (GNP) and multi-walled carbon nanotube fillers (MWCNT) were simultaneously added to a polycarbonate matrix, in an attempt to improve thermal conductivity. Thermal conductivities of the composites were measured at room temperature. Results show that MWCNTs can improve thermal conductivity by filling gaps between GNPs. Additionally, a small amount of well dispersed MWCNTs increased thermal conductivity by 23% compared to composites containing only GNPs....
