Topological and morphological signatures of disorder in a self-assembled, soft matter sponge network
Xueyang Feng, Suman S. Kulkarni, Michael S. Dimitriyev +4
Many soft matter systems exhibit ordered, polycontinuous network morphologies, such as the cubic (double) gyroid or diamond, as well as disordered network morphologies known generi…
An Orbifold Framework for Classifying Layer Groups with an Application to Knitted Fabrics
Sonia Mahmoudi, Elizabeth J. Dresselhaus, Michael S. Dimitriyev
Entangled structures such as textiles and architected materials are often doubly periodic. Due to this property and their finite transverse thickness, the symmetries of these mater…
Structural Relaxation and Anisotropic Elasticity of Ordered Block Copolymer Melts
Krista G. Schoonover, Gaurav Rawat, Emily B. Pentzer +1
Block copolymer (BCP) melts play a critical role in the design of thermoplastics, owing in large part to the creation of alternating nano-scale domains of soft and stiff components…
Not even metastable: Cubic double-diamond in diblock copolymer melts
Micheal S. Dimitriyev, Benjamin R. Greenvall, Rejoy Matthew +1
We study the thermodynamics of continuous transformations between two canonical, cubic network phases of block copolymer melts: double-gyroid, an equilibrium morphology for many sy…
Chirality Effects in Molecular Chainmail
Alexander R. Klotz, Caleb J. Anderson, Michael S. Dimitriyev
Motivated by the observation of positive Gaussian curvature in kinetoplast DNA networks, we consider the effect of linking chirality in square lattice molecular chainmail networks…
Mesoscale Polymer Arrays: High Aspect Ratio Surface Structures and Their Digital Reconstruction
Demi E. Moed, Michael S. Dimitriyev, Benjamin R. Greenvall +2
Inspired by adhesive bio-filamentous structure, such as bacterial pili, this work details the methods used to fabricate and characterize a surface-anchored array of thin, flexible…
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…
Block Copolymer Double Diamond Twin
Xueyan Feng, Michael S. Dimitriyev, Edwin L. Thomas
A twin boundary (TB) is a common low energy planar defect in crystals including those with the atomic diamond structure (C, Si, Ge, etc.). We study twins in a self-assembled soft m…
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…
End exclusion zones in strongly stretched, molten polymer brushes of arbitrary shape
Michael S. Dimitriyev, Gregory M. Grason
Theories of strongly stretched polymer brushes, particularly the parabolic brush theory, are valuable for providing analytically tractable predictions for the thermodynamic behavio…
Swelling thermodynamics and phase transitions of polymer gels
Michael S. Dimitriyev, Ya-Wen Chang, Paul M. Goldbart +1
We present a pedagogical review of the swelling thermodynamics and phase transitions of polymer gels. In particular, we discuss how features of the volume phase transition of the g…
