Ion partitioning and behavior in electrolyte solutions plays an important role in drug delivery and therapeutics, protein folding, materials science, filtration and energy applications such as supercapacitors. Here we show that the segregation of ions in solutions also plays an important role in the exfoliation of natural flake graphite to pristine graphene. Polarizable anions such as iodide and acetate segregate to the interfacial region of the aqueous phase during solvent interfacial trapping…
