Abstract

A cobalt nanoparticle-graphene composite was synthesized by using mechanical milling and sonication assisted exfoliation. Graphite powder and cobalt metal powder in the ratio of 4:1 by weight was first mechanically milled for 60 hrs. in Toluene medium. The milled powder was then exfoliated by using sodium lauryl sulfate surfactant to produce cobaltgraphene nano composite. The composite have shown good magnetic property due to the presence of cobalt nanocrystals and this was confirmed by vibrating sample magnetometer (VSM). Due to the sonication-assisted exfoliation, few layers of graphene formed which were confirmed by Raman spectroscopy, x-ray photo electron spectroscope (XPS) and atomic force microscopy. Phase analysis and size of the cobalt-graphene nano composite was calculated with the help of x-ray diffraction pattern and transmission electron microscopy
