Résumé
Herein, tuning polyelectrolyte-graphene interaction was demonstrated to enhance electrocatalytic activity for non-enzymatic hydrogen peroxide detection. The introduction of positively charged poly(diallyldimethylammonium chloride) (PDDA) onto graphene surface not only prevent the aggregation of graphene sheets through electrostatic repulsion but also create net positive charge on adjacent carbon atoms in the graphene due to the occurrence of the intermolecular charge transfer by virtue of the robust electron-withdrawing ability of PDDA. Notably, we revealed the influence of the adsorbed polyelectrolytes on the redox of H
