Thermal conductivity of epoxy composites modified by microspheric molybdenum disulfide

In order to improve the thermal conductivity of epoxy resins (EP) without damaging their dielectric properties, a kind of molybdenum disulfide with microspheres structure (S-MoS2) was used as modifiers to add into EP matrix, which were prepared via the surfactant promoting hydrothermal process, and a new kind of S-MoS2/EP composites was finally obtained. The morphology of the prepared S-MoS2 was observed by X-ray diffraction (XRD) scanning electron microscopy (SEM), while the influence of different S-MoS2 loading on the dielectric properties, thermal conductivity and thermal resistance of S-MoS2/EP composites was also researched. The results suggested that the reasonable content of S-MoS2 can highly improve the thermal conductivity of S-MoS2/EP, which can be attributed to the excellent thermal resistant and uniform dispersion of S-MoS2 in EP matrix.
