Non-affinity of liquid networks and bicontinuous mesophases
Michael S. Dimitriyev, Xueyan Feng, Edwin L. Thomas +1
Amphiphiles self-assemble into a variety of bicontinuous mesophases whose equilibrium structures take the form of high-symmetry cubic networks. Here, we show that the symmetry-brea…
Chain trajectories, domain shapes and terminal boundaries in block copolymers
Benjamin R. Greenvall, Michael S. Dimitriyev, Gregory M. Grason
The packing geometry of macromolecules in complex mesophases is of key importance to self-organization in synthetic and biological soft materials. While approximate or heuristic mo…
Medial packing, frustration and competing network phases in strongly-segregated block copolymers
Michael S. Dimitriyev, Abhiram Reddy, Gregory M. Grason
Self-consistent field theory (SCFT) has established that for cubic network phases in diblock copolymer melts, the double-gyroid (DG) is thermodynamically stable relative to the com…
Medial packing and elastic asymmetry stabilize the double-gyroid in block copolymers
Abhiram Reddy, Michael S. Dimitriyev, Gregory M. Grason
Triply-periodic networks are among the most complex and functionally valuable self-assembled morphologies, yet they form in nearly every class of biological and synthetic soft matt…
