Development of Epoxy-MgO Nanocomposite Material for High Voltage Electrical Insulation

Abstract: This paper investigates the dielectric properties of epoxy-MgOnanocompositematerials,focusingontheirdielectric constant and breakdown strength. The synthesis of epoxy-MgO nanocompositeswithvaryingnanoparticleconcentrationsusing magneticstirring ,ultrasonication and thermalcuring willbe done. Keyparametersincluding dielectric constantandbreakdownstrength, willbeevaluatedthroughhighvoltagetesting toassessperformanceofthematerialunderelectricalstress. Thisproject will also evaluatethecost-effectiveness ofepoxyas a polymer matrix, being more affordable and accessible than other polymers; making it suitable for large-scale applications. Additionally,theeffectsofnanoparticledispersionandinterfacial interactions on dielectric characteristics will be explored to identifyoptimalloadingconditions.Theresultingnanocomposites with enhanced dielectric properties could make them promising candidates for high voltage electrical insulation, where high dielectric strength and thermal stability are critical.
