Abstract

Equilibrium properties of mesogels-supermolecular networks, formed by symmetrical triblock copolymers with ionizable central blocks-are considered by scaling and self-consistent-field (SCF) arguments. We use the analogy between swelling elements of mesogels and polymer brushes to predict the swelling in selective solvents and deformational behavior of mesogen. It is showun that equilibrium interdomain distances in charged mesogels of various morphologies obey universal scaling laws. Educing the solvent strength leads to an abrupt collapse of mesogen (phage transition of the first order) far below the θ point. A detailed analysis of the intrinsic structure of lamellar mesogel is carried out within a SCF theory
