Reduced graphite oxide films obtained using NaBH4 exhibit much lower sheet resistance than films obtained using N2H4 because the latter results in the formation of C–N groups, which may act as donors compensating the hole carriers in the film and increasing resistivity. A transparent conducting film prepared using optimized NaBH4 reduction reveals a sheet resistance comparable to that observed in dispersed graphene.
