N2 - Block copolymers act as surfactants in mixtures of two immiscible, inversely selective solvents. The copolymer aggregates at the liquid-liquid interface, leading to the formation of stable microemulsion droplets. Scaling arguments are employed to evaluate the free energy of a single, spherical diblock copolymer aggregate by accounting for the dependence of monomer density on radial distance. The aggregation number and interface curvature are found to be a strong function of the core block molecular weight, and only to a lesser degree of the interfacial tension.
