Abstract

A Nickel nanocrystal � Graphene composite was synthesized by using mechanical milling and sonication assisted exfoliation. Graphite powder and Nickel 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 Nickel � Graphene nano composite. The composite have shown good magnetic property due to the presence of Nickel 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. The size, Phase identity and composition of the Nickel nanocrystal in the composite was calculated with the help of X-Ray Diffraction pattern and Transmission Electron Microscopy.
