Improvement of Thermal Conductivity of Nano MgO/Epoxy Composites for Electrical Insulation Materials.

In the present study the dielectric and thermal properties of nano and micro MgO / Epoxy composites were studied with different weight percentage ratios, aiming at the development of electrical insulating materials with high thermal conductivity, this can be achieved by adding a low concentration of thermally conducting but electrically insulating nanofillers such as MgO nanoparticles, the results are discussed by determining the relative permittivity, tan delta and the thermal conductivity of the tested specimens. The obtained results showed improvement in the thermal conductivity values without deteriorating the dielectric properties. [ABSTRACT FROM AUTHOR]
