The effects of a uniform electric field on the interfacial properties of a model dipolar fluid were studied using a modified mean-field density functional theory. Both density and orientational order-parameter profiles of the planar vapor-liquid interface were obtained. The electric field can shift the surface tension for the dipolar fluids with reduced dipole moment. The electric field was also found to reduce the thermodynamical surface tension but enhances the mechanical surface tension. The field strength is estimated to detect these field effects.
