Abstract:
Graphene, a one-atom-thick two-dimensional (2D) single layer of sp2-bonded carbon, has garnered much attention in the field of material science in recent years because of its extraordinary electrical, thermal, mechanical, and structural properties. These unique and intriguing features make this highly versatile carbon material promising in many potential applications such as nanocomposites transparent conducting films, sensors, super capacitors nanoelectronics batteries and so on. Graphene and graphene oxide (GO) based nanocomposites have attracted tremendous attentions due to their many excellent properties arising from either the components themselves or functionalization and energy. Magnetic nanoparticles are most investigated nanomaterials systems due to their magnetic properties depend on their shape, size and morphology. Several factors are responsible for the unique properties of magnetic nanomaterials such as finite size effects due to the quantum confinement of the electrons inside the material. In this work, CO3O4/graphene oxide nanocomposites have been prepared by hydrothermal method with at different concentration of CO3O4 . The phase formation of the compound is confirmed using XRD technique and found that the CO3O4 NPs of size 23 nm were dispersed on to graphene sheets .The surface of morphology of the compounds is studied at different magnification at room temperature using SEM and TEM techniques. Study of magnetic properties of nanocomosites by VSM technique which shows the superparamanetic behavior of magnetic nanocomposites and study of surface morphology and surface potential of these nanocomposite thin films is carried out using scanning Kelvin probe (SKP) microscopy.
