In Monolayered graphene when dipped in an electrolyte, eventually an EDL layer will be forming at the ionic interface.
So its important for the selection of elecetrolyte and electrode for this particular process to be conducted. This enables us to understand there will be a changing barrier potential according to the electrolyte to perform the act of diffusion. My opinion is that if HDL is considered we need a steady current is needed.
Is it true that HDL is formed by the adsorbed ions? This question to me was necessary for the understanding of sticking together of graphene layers in an aqueous medium - the question is how ions are adsorbed on these surfaces, if there is HDL already present. Or maybe HDL is formed by these adsorbed ions?
Maybe adsorbed ions interacts with the field of HDL formed by other adsorbed ions?
