Mechanical, thermal and dielectric properties of hybrid composites of epoxy and reduced graphene oxide/iron oxide
Abstract
A hybrid filler (RGO–Fe<sub>2</sub>O<sub>3</sub>) composed of inorganic nanoparticles of iron oxide (Fe<sub>2</sub>O<sub>3</sub>) on reduced graphene oxide nanoplatelets (RGO) was successfully synthesized using a microwave assisted chemical reaction. Incorporating RGO–Fe<sub>2</sub>O<sub>3</sub> in epoxy through in situ polymerization afforded RGO–Fe<sub>2</sub>O<sub>3</sub>/epoxy composites. Thermogravimetric analysis demonstrated the thermal stability of RGO–Fe<sub>2</sub>O<sub>3</sub>/epoxy composites. Improved property profiles of RGO–Fe<sub>2</sub>O<sub>3</sub>/epoxy were established through electrical conductivity measurements and dielectric properties in the range 40 Hz to 30 MHz and at microwave frequencies in the S band (2–4 GHz) region. Mechanical property measurements were also performed. Dielectric constant, electrical conductivity and absorption coefficient of RGO–Fe<sub>2</sub>O<sub>3</sub>/epoxy composites were found to be much higher than that of the neat epoxy matrix. Addition of 0.25 phr RGO–Fe<sub>2</sub>O<sub>3</sub> increased the tensile strength, flexural strength and impact strength by 56%, 81% & 112% respectively. Fracture toughness determined using single-edge notch three-point-bending specimens also showed an impressive enhancement. Microstructure studies like scanning electron microscopy and transmission electron microscopy demonstrated good interfacial adhesion, the underlying reason for overall improvement in mechanical properties.
