Rubber carbon black (CB)/rubbery epoxy (RE) and CB/silicone composites with different types, loadings, and silane functionalization of carbon black were prepared. These composites were investigated for their electrical conductivities, and their mechanical properties. The thermal conductivity of each composite was also determined using a thermal constants analyzer. It was determined that the incorporation of carbon black into the composites increased the thermal conductivity in all of the samples. ...
The effects of the addition of three different fillers to a polymer matrix on the thermo-physical properties of the resulting composites were investigated by the authors. Boron nitride, synthetic diamond, and silicon nitride were used as the fillers (up to 2 vol. %), and it was found that their addition did increase the thermal conductivity relative to that of the pure epoxy matrix. Furthermore, it was determined that the thermal conductivities of ...
Polyactic acid (PLA)-micro hexagonal boron nitride (hBN)-graphene nanoplatelet (GNP) polymer composites were prepared, and the effects of varying filler contents on the thermal and mechanical properties of the polymer composites were investigated. It was determined that the addition of the GNPs resulted in a decrease in thermal conductivity in comparison to a PLA-hBN composite unless the GNP:hBN ratio was 1:1, where the thermal conductivity was equal to that ...
The thermal conductivity and dynamic viscosity of Al2O3-ethylene glycol and TiO2-ethylene glycol nanofluids have been determined as a function of the nanoparticle volume fraction (from 1 to 3 %) and temperature. It was determined that the thermal conductivity increased with increasing temperature as well as with increasing particle volume fraction for both types of nanofluids, but increasing the particle volume fraction caused a more significant increase than increasing the temperature. ...
Epoxy nanocomposites containing thermally reduced graphene oxides (TRGs) with different oxygen contents were prepared and their mechanical and thermal properties were investigated. It was found that increasing the number of oxygen containing groups on the TRGs resulted in reduced agglomeration of the graphene oxides within the epoxy matrix. Therefore, in samples with a higher oxygen content, a higher interfacial contact area is present between the organic and inorganic phases in ...
