Abstract
We consider the instability of amphiphilic sponge phases with respect to a fluctuating lamellar phase in a consistent random interface model based on the curvature-elastic Hamiltonian of the membranes. The phas e behavior is investigated in terms of bending moduli and surfactant c oncentration. First-order transitions are found upon changes in surfac tant concentration, bending modulus, or saddle-splay modulus in agreem ent with experimental observation.
