Reduced Graphene Oxide (rGO) has been successfully synthesized from
Graphite powder through chemical process using modified Hummers method by
removing NaNO3 from reaction formula. Hydrazine hydrate 80 wt% has been chosen
as reductor to eliminate the epoxy group in GO. FTIR and Uv-Vis spectroscopy result
showed that Graphene Oxide (GO) and rGO were formed. Our produced rGO then
used to fabricated the composite thin film rGO/PEDOT:PSS by spin coating at room
temperature. The optical constant of thin film rGO/PEDOT:PSS were calculated from
the absorbance spectrum of Uv-Visible spectra. The result showed that the value of
coefficient absorbance of rGO dropped from 4.7 106 m
-1
to 1.3 106 m
-1
after doped
with 0.02 mL PEDOT:PSS, then increase with the addition volume concentration of
PEDOT:PSS. The value of extinction coefficient decrease from 0.31 to 0.08 after rGO
doped with 0.02 ml PEDOT:PSS and then increase with the addition concentration of
PEDOT:PSS. Our result show that thin film rGO/PEDOT:PSS was more transparent
than that of thin film rGO.
