Abstract
Self-consistent field theory is applied to study the ordering behavior of triblock copolymer solutions. A unit cell approximation is used that provides information about individual micelles but does not provide information about the 3-dimensional packing of the micellar aggregates. Information obtained from this approach includes the preferred micellar geometry (spheres, cylinders, or lamellar), the aggregation number, bridging fraction, osmotic pressure, and form factor for a scattering experiment. A variety of general conclusions are obtained with regard to the relationships between these quantities and the polymer concentration, end block solvent quality, and relative molecular weights of the different copolymer blocks.
