Cobalt ferrite has remarkable electro-magnetic properties, high chemical and thermal stability, and broad technological applications while graphene and its hybrid materials have impressive mechanical, thermal, and electrical properties coupled with extraordinarily increased specific surface area and low density. In this study, reduced graphene oxide (rGO)/cobalt ferrite composites were prepared via polyol co-precipitation method using two different routes: conventional and microwave heating. Both materials, Cobalt nitrate and ferric chloride, were used as the starting materials were mixed with pre-determined amount of graphene content to obtain different samples compositions ranging from 0wt.% to 30wt.% of rGO. Diethylene glycol acted as a high boiling point solvent and a reducing agent. The prepared samples were characterized via SEM, TEM, XRD FTIR and VSM. Samples showed improved purity, properties and crystallinity with microwave heating as compared to the conventional heating procedure. Magnetic properties were found to be tunable depending upon graphene content and synthesis method.
