Zeta-potential versus pH curve for rGO-NH.
• Amount of NH groups
In order to estimate the amount of NH groups in rGO-NH a reaction with 4-bromobenzyl chloride was performed and the Br amount was quantified by X-ray fluorescence spectroscopy. The value obtained corresponds to 0.13 mmol/g.
• Conductivity
Conductivity of pressed pellets of rGO-NH is 70.75 S/m.
