Abstract

Insertion of 3-hydroxypropanesulfonicacid (HPS) in the graphene oxide (GO) interlayer results in high proton conductivity (10^-2 -10^-1 S cm^-1 ), owing to an improvement in oxygen content, interlayer distance and water absorbing capacity. This result indicates that hydroxyalkylsulfonicacids can be perfect guest molecules for improving the proton conductivity of carbon materials.

Keywords: conducting materials; graphene; host-guest systems; proton conductivity; superconductors.
