LDOT Diblock Copolymers: Specific Interactions, Compressibility, and Fluctuations

We perform the recently developed compressible Hartree analyses on the phase behavior of LDOT-type diblock copolymers based on polystyrene and homologous poly(n-alkyl methacrylates).~ Specific interactions between dissimilar monomers, compressibility difference between block components, and concentration fluctuations are all considered to illuminate the complicated phase behavior of those homologous copolymers.~ Microphase transition temperatures and their pressure dependence are compared with the corresponding theoretical values for the copolymers.~ We provide suggestions for the design of a better nanostructured material using those copolymers.
