Abstract
Highly conductive reduced graphene oxide (GO) polyimide nanocomposites are synthesized by a well-organized in situ thermochemical synthesis technique. The surface functionalization of GO was carried out with aryl diazonium salt including 4-iodoaniline to form phenyl functionalized GO (I-Ph-GO). The thermochemically developed reduced GO (R-I-Ph-GO) has five times higher electrical conductivity (42,000 S/m) than typical reduced GO (R-GO). We also demonstrate a R-I-Ph-GO/polyimide (PI) composites having more than 104 times higher conductivity (~1 S/m) compared to a R-GO/PI composites. Finally, our on-going researches with functionalized GO (I-Ph-GO) and applications will be introduced and discussed.
