Preparation of ferrocenyl-furan modified graphene oxide via Diels-Alder click reaction and using of its polypyrrole nanocomposites as supercapacitor electrode material

In the present study, the 1-(2-furyl)acryloylferrocene was prepared as a suited scaffold for Diels-Alder reaction with graphene oxide. In order to increasing of conductivity, the ferrocenyl functionalized graphene oxide (GOFcFu) was physically mixed with polypyrrole. Polypyrrole as an organic polymer was obtained by oxidative polymerization of pyrrole. The obtained GO-FcFu/PPy nanocomposite were tested as hybrid supercapacitor with dual features of electrical double layer capacitance and pseudocapacitive arising from GO and ferrocene species, respectively. The improved surface area (33.41 m(2) g(-1)), high mass specific capacity of 231.31 mAh g(-1) (1 A g(-1)), and the capacity retains 89% of initial capacity after 5000 cycles were estimated the sufficiency of final composite for use as electrode material.

Automated summary

In this study, 1-(2-furyl)acryloylferrocene was used as a scaffold for the Diels-Alder reaction with graphene oxide. A ferrocenyl-functionalized graphene oxide (GOFcFu) was physically mixed with polypyrrole to increase the conductivity. The resulting GO-FcFu/PPy nanocomposite showed both electrical double layer capacitance and pseudocapacitance, making it suitable for use as an electrode material in a hybrid supercapacitor.
