Graphene oxide (GO) reduction is a promising way for graphene l
arge scale synthesis.
Pre-exfoliated graphite was oxidized and reduced. The material w
as compared to commercial
graphene oxide and its reduced sample. The reduction process of grap
hene oxide is accomplished
using sodium borohydride (NaBH
4
) with variable-valence metal ion – cobalt – assistance. The
reduced graphene oxide (RGO) was characterized by Raman sp
ectroscopy. The particle size and
suspension stability were determined. Electrical conductivity me
asurements of GO and RGO
samples have been done in temperature range from -150°C to 85°C. Pre
-exfoliation effect was
determined.
