Heyi Liang, Zilu Wang, and Andrey V. Dobrynin We use coarse-grained molecular dynamics simulations to establish correlations between peak position in the static structure factor S(q) of combs and bottlebrushes in a melt and their architectural parameters such as the … Read more
Michael Jacobs, Heyi Liang, Erfan Dashtimoghadam, Benjamin J. Morgan, Sergei S. Sheiko, and Andrey V. Dobrynin While chain branching generally promotes swelling of polymer networks, it also leads to nonlinear modulus increase with network expansion. To understand the effect of … Read more
Heyi Liang, Zilu Wang, Sergei S. Sheiko, and Andrey V. Dobrynin We have studied properties of comb-like and bottlebrush-like graft copolymers made of chemically different backbones and side chains in a melt. A diagram of states for this class of … Read more

Ivanov ABA triblock copolymers composed of a poly(dimethylsiloxane) (PDMS) bottlebrush central block and linear … Read more
Heyi Liang, Benjamin J. Morgan, Guojun Xie, Michael R. Martinez, Ekaterina B. Zhulina, Krzysztof Matyjaszewski, Sergei S. Sheiko, and Andrey V. Dobrynin A combination of scaling analysis and rheological experiments was used to study correlations between the entanglement plateau modulus … Read more
Michael Jacobs, Heyi Liang, Brandon Pugnet, and Andrey V. Dobrynin Understanding the surface properties of polymer melts is crucial for designing new polymeric coatings, adhesives, and composites. Here, we study the effect of molecular architecture on surface and interfacial tension … Read more
Sergei S. Sheiko, Matthew H. Everhart, Andrey V. Dobrynin, Mohammad Vatankhah-Varnosfaderani By controlling polymer-network architecture, we outline a roadmap for the creation of tissue-like materials to extend the performance of soft robots to harsh environments. Read Article
Mohammad Vatankhah-Varnosfaderani, Andrew N. Keith, Yidan Cong, Heyi Liang, Martin Rosenthal, Michael Sztucki, Charles Clair, Sergei Magonov, Dimitri A. Ivanov, Andrey V. Dobrynin, Sergei S. Sheiko Active camouflage is widely recognized as a soft-tissue feature, and yet the ability to … Read more
Heyi Liang, Sergei S. Sheiko, and Andrey V. Dobrynin Using a combination of the scaling analysis and molecular dynamics simulations, we study relationship between mechanical properties of networks of graft polymers and their molecular architecture. The elastic response of such … Read more
