摘要
A theory of a confined two dimensional electrolyte is presented. The positive and negative ions, interacting by a potential, are constrained to move on an interface separating two solvents with dielectric constants and . It is shown that the Debye-H\"uckel type of theory predicts that the this 2d Coulomb fluid should undergo a phase separation into a coexisting liquid (high density) and gas (low density) phases. We argue, however, that the formation of polymer-like chains of alternating positive and negative ions can prevent this phase transition from taking place.
