Understanding the dielectric properties of epoxy molybdenum disulfide nanocomposites

An attempt has been made to understand the surface discharge resistance of epoxy molybdenum disulphide nanocomposite material under AC and DC voltages. To characterize the material, surface charge accumulation studies and basic dielectric properties of the material viz., permittivity and tan(𝛿) of the material were carried out. Also the level of degradation of insulating material characterized through contact angle measurement and by surface roughness measurements. The results of the study conclude that 0.5 wt% of epoxy nanocomposites showed high discharge resistance.
