Abstract
We report the synthesis and characterization of Manganese doped Cobalt oxide porous nanoparticles loaded epoxy matrix composites possessing enhanced dielectric properties. The amine functionalized mesoporous Mn-Co3O4 synthesized through sol–gel method using SBA 15 as hard template and the obtained product is subjected to XRD, SEM and TEM studies to confirm the crystal structures. The prepared nanocomposites of mesoporous Mn-Co3O4 nanoparticles and Mn-Co3O4well dispersed epoxy are characterized using DSC, TGA, SEM and electrical properties. The thermal properties of mesoporous 3% Mn-Co3O4 epoxy Nanocomposite samples showed a significant enhancement in thermal stability than that of neat epoxy matrix. The Glass transition temperature of 3% Mn-Co3O4 epoxy Nanocomposite is 171 °C, the 10% weight loss temperature was found to be 310 °C and the chair yield at 800 °C is 31%. The mesoporous Mn-Co3O4 incorporated epoxy composite exhibited high electrical conductivity, low dielectric loss and reduction in resistivity when compared to neat epoxy.
