Abstract

In this research work we prepared nanomaterial and checked its chemical properties. The preparation of
nanomaterial is done with two different methods one is fusion method and other is solution method. Two samples were
prepared first is G 475 and other is G 600 which means, at 475°C and 600°C. For the characterization of nanomaterial
we used XRD, Raman Spectroscopy, TGA, TEM and Elemental analysis. We have tested different chemical properties for
this nanomaterial, properties such as thermal stability, electrical conductivity, Crystallanity, oil absorption value. The
minimum oil absorption value of nanomaterial i.e. G-475 is found to be 11.94 gm. Both the product G 475 and G 600
shows there peak at 2ϴ value is 26 and corresponding basal spacing i.e. d-spacing is at 2.035 A0
. The percentage
crystallinity of both that is of G 475 and G 600 is found to be 5.57 and 5.18.These confirms the presence of graphene
with fusion method, while in solution method it shows the peak at 2ϴ the value is 26 and corresponding basal value that
is d- spacing of the nanomaterial is 3.548A0
. The percentage crystallinity of the nanomaterial is found to be 5.10.These
shows that the material is good crystalline material and having a uniform distance. The thermal analysis gives an idea
about its thermal stability. The result shows that nanomaterial is stable up to 4000C. But at 4750C the weight loss is
observed and it is less, that means the hydrogen content is more. At 6000C the weight loss is more means the hydrogen
content is less and the carbon content is most with small amount of hydrogen content. Raman Spectroscopy shows the
graph between the range of 1560 cm
-1
and 1360 cm-1
, it indicates that the carbon material is present in the nanomaterial
and it has exactly the peak as like of graphene. We tested electrical conductivity of both the nanomaterial it shows that
they have electrical conductance. The nanomaterial G 600 has a greater conductance than G 475.The TEM images
shows the 2 D membrane structure. Both the samples G 475 and GS 600 are closely pack to each other and there is no
transparency found in the material.
