In one aspect, a composite membrane comprises a polymeric host comprising polybenzimidazole or polybenzimidazole derivative and graphene oxide dispersed in the polymeric host, the graphene oxide at least partially functionalized with phosphonic acid moieties, phosphonate moieties or combinations thereof. In some embodiments, the functionalized graphene oxide is homogeneously dispersed in the polymeric host and/or is not agglomerated in the polymeric host.
