Graphene oxide based conductive glue as a binder for ultracapacitor electrodes

An adhesive and conductive glue was created by synergistic assembly of graphene oxide (GO), single walled carbon nanotubes (SWCNTs) and conjugate polymer PEDOT:PSS in aqueous solution. The GO–SWCNTs–PEDOT:PSS glue can be used as a binder to fabricate metal oxide nanoparticle based ultracapacitors. Since the functional nanoparticles are immersed in this conductive gel, uniform electrical and mechanical interconnect can be achieved, leading to enhanced performance of ultracapacitors.
