In present work, the dielectric properties of two different nanoparticle loaded Bisphenol A-epoxy resin were carried out at room temperature. Sample of the neat epoxy resin and nanoparticle loaded epoxy resin in the form of disc were prepared of different weight fraction (i.e 0.5 wt%,0.7 wt%,1 wt%,1.5 wt%,1.7 wt%,2 wt%). TiO2 and Al2O3 nanoparticles were taken as filler in the epoxy resin. Complex permittivity of the prepared samples was measured using Agilent E4980A precision LCR meter in frequency range of 103 Hz to 106 Hz. The dependency of dielectric behavior on type and concentration of nanoparticle in considered frequency range are discussed in detail.
