Abstract
Graphene oxide–polyaniline composites were synthesized by an interfacial method using two green solvents, water and an ionic liquid (1-butyl-3-methylimidazolium tetrafluoroborate), as the two phases. The interfacial polymerization of aniline was carried out at room temperature in the presence of graphene oxide dispersed in the aqueous phase. The analysis revealed the surface of the graphene sheets to be coated with a smooth thin layer of polyaniline. The thermal stability of the composites was much better than that of bare graphene oxide. The composites were used to modify the glass carbon electrodes for the chemical detection of hydrogen peroxide in aqueous media. This method is a facile, efficient, and green route for the development of doped polyaniline materials suitable for chemical sensors.
