【 摘 要 】

A high dielectric stable epoxy composite was prepared and characterized for their dielectric response and charge transfer properties at elevated temperatures. The principal aim of this work is to develop high stable (insulative) particle dispersed epoxy composites for high temperature and structural applications. The Fe-O single crystal was prepared via co-precipitation and surface capped by capping agent to restrict the abrupt mobility of electrons. The dielectric results show that addition of Fe-O into epoxy resin increase the charge transfer up to 7.4 (dielectric constant). Whereas addition of silane capped FeO particles not altered the dielectric constant and conductance. The increase of temperature on dielectric fetched more dissipation but in surface capped FeO dispersed composite its lower. The addition of surface capped Fe-O particle dispersed epoxy resin composite gives improved mechanical strength than as-received one. The SEM and TEM morphological behaviour confirms the uniform dispersion and adhesion of Fe-O particles on matrix. These mechanically toughened high stable dielectric epoxy composites could be used in VLSI and embedded board fabrication industries because of their better insulation properties even in high temperature.
