Abstract

The effect of dispersion agent, the content and size of nanoparticle on the mechanical and thermal properties has been investigated in $TiO_2$ nanoparticle/epoxy resin composites(nanocomposites). The weight fraction of fabricated nanocomposites were 0, 1, 3, 5%, respectively. The glass transition temperature was lower than pure epoxy resin and decreased with the increasing of nanopaticle content. This is considered that the cross link of epoxy resin during solidification was hindered by the presence of nanoparticles. Nanocomposites of 3wt% content with dispersion agent showed the best tensile strength. The tensile strength of 20㎚ $TiO_2$ nanocomposites were higher than one of 200nm $TiO_2$ nanocomposites.
