Titanium dioxide nanoparticles were synthesized in an aqueous solution. They were dispersed into an epoxy polymer matrix (commercially available under the trade name Araldite 5808) using a planetary mixer. Nanocomposite materials were prepared with several weight loadings of nanoparticles In this work we Investigate the effects of the particle agglomeration on the mechanical and electrical properties of the composites. The structure of the composites was probed by transmission electron microscopy (TEM). For investigating the mechanical properties, a dynamical mechanical analysis (DMA) was employed. The dielectric breakdown strength and the impedance response were also measured in order to characterize the insulating properties of the nanocomposites and their potential use in high voltage applications.
