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 cobalt-
graphene 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.
