Abstract: Abstract The graphene oxide (GO) nanosheets/carboxyl-functionalized multi-walled carbon nanotubes (CNTs) hybrids (GO/CNTs) were synthesized via vacuum filtration solution hybrid dispersion and the corresponding GO/CNTs/polyimide (GO/CNTs/PI) nanocomposite films were facilely prepared by in situ polymerization. Both… read more here.
