Intrachain Ordering and Segregation of Polymers under Confinement
We study the relationship between intrachain ordering and segregation tendency of two polymers confined in a cylindrical space. We find the chains segregate spontaneously even outside de Gennes’ linear-ordering scaling regime, in which each chain is a linear array of blobs. When the chains are weakly compressed against each other, linear ordering is well preserved and the chains remain segregat...

متن کاملTriblock Copolymer Theory: Free Energy, Disordered Phase and Weak Segregation
We derive an order parameter model for triblock copolymers. After the statistical description of interacting polymer chains is presented, the self-consistent field theory is used as a variational approximation method to obtain a free energy minimization problem with respect to effective potential fields. We then identify the monomer densities under such fields as order parameters and view the f...
متن کاملPolymer Conformation under Confinement
The conformation of polymer chains under confinement is investigated in intercalated polymer/layered silicate nanocomposites. Hydrophilic poly(ethylene oxide)/sodium montmorillonite, PEO/Na+-MMT, hybrids were prepared utilizing melt intercalation with compositions where the polymer chains are mostly within the ~1 nm galleries of the inorganic material. The polymer chains are completely amorphou...
