In this paper, polyamide (PA, composed of at least 60% renewable materials) was used as a polymer matrix to prepare PA-hexagonal boron nitride (hBN) polymer composites with varying hBN contents. Two different PA samples were used in this study: a low viscosity grade PA (PA-30), as well as a high viscosity grade PA (PA-90). The composite polymers were tested to evaluate their thermal, physical, and mechanical properties. It was concluded that ...
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 ...
Graphite nanoplatelets were dispersed in varying quantities into a silicone matrix to form composite materials with higher thermal conductivities than the pure silicone matrix without sacrificing mechanical properties. It was found that the thermal conductivities of the composites increased with increasing GNP content as well as with increasing GNP particle size. The composites were found to be effectively electrically insulating, and it was found that the addition of GNP did ...
A chalcogenide glass was prepared and doped with carbon nanotubes (CNTs) in an effort to increase the electrical and thermal conductivity of the glass. The glass that was used in this study was Se85Te10Ag5 which was prepared by melt-quenched method. CNTs were added to the glass at 3 and 5 wt. % and the properties of the composite glasses were compared with those of the pure chalcogenide glass. It was found ...
Nanocomposite phase change materials (PCMs) were prepared by adding silver nanoparticles to isotactic polypropylene (iPP) and an iPP/paraffin wax phase change materials. The Ag nanoparticles were found to be well dispersed in both iPP and the iPP/wax composite, and filler agglomeration was found to increase with increasing filler content. The nanoparticles did not significantly affect the modulus of the iPP on its own, but when Ag and paraffin ...
