Abstract
Although single surfactants rarely form vesicles spontaneously, mixtures of two surfactants can lead to spontaneous vesicle formation. By considering the curvature elasticity of the surfactant bilayer, we show theoretically how the energetic stabilization of mixed vesicles can occur. Interactions between the two species (of the proper sign and magnitude) are crucial to stabilizing these vesicles. These interactions lead to composition asymmetries and effective spontaneous curvatures of the inner and outer layers that are of equal and opposite signs.
