Development of a Novel Sulfanilic Graphene Oxide Composite: Ozonated Sulfanilic Graphine Oxide (OSGO)

Graphene oxide(GO) contains several chemical functional groups that are attached to the graphite basal plane and can be manipulated to tailor GO for specific applications through chemical reactions. Ozonation of the graphite oxide has been noted to increase the degree of oxidation, hence increase in hydroxyl,laxtol , ester and ketone content in GO. The increase in proton conductivity is attributed to the higher content of ozonated functional groups in the basal planes and edges of the ozonated GO. Substituting hydroxyl/epoxy groups of GO with –HSO3 group enhances it activity, nano composites based on sulfonated graphene oxide (SGO) and sulfonated poly (ether sulfone)(SPES) have been noted to improve proton conductivity and ion exchange capacity . Herein is description development of novel ozonated sulfonated graphene oxide (OSGO).
