Abstract
Here we extend the theoretical analysis presented in the previous paper to the case where the dipolar fluid is contained between charged walls, with all entities possessing dispersion attractions. A Stockmayer model representing hydrogen chloride is used for the fluid and the wall parameters are chosen to mimic solid carbon dioxide. The effect of an electric field on the capillary condensation of an HCl gas is investigated. At lower temperatures a solid-like layering transition seems to occur and here we observe interesting structural changes in that phase for variations of both the electric field and of the distance between the walls.
