Nanotetrapods Promote Polymer Flow Through Confinement-Induced Packing Frustration

Published in Nature Communications, vol. 16, article 8550, 2025

Mixing tetrapod-shaped nanoparticles into a polymer melt can make it flow more easily: the inner curvature of nanotetrapods imposes strong physical confinement on nearby chains, creating a packing frustration that increases polymer mobility and lowers viscosity — in contrast to compact particles like spheres or rods, which tend to thicken the melt.

Sequence-Defined Pareto Frontier of a Copolymer Structure

Published in Journal of Polymer Science, vol. 60, no. 14, pp. 2100–2113, 2022

The correlations between the sequence of monomers in a macromolecule and its three-dimensional (3D) structure is a grand challenge in polymer science. The properties and functions of macromolecules depend on their 3D shape that has appeared to be dictated by their monomer sequence. To address this problem, we combine evolutionary computing and coarse-grained molecular dynamics (CGMD) simulation and study the sequence-structure correlations of a model AB-type copolymer in solution, and assess the impact of sequence on packing density in its bulk phase. The CGMD-based evolutionary algorithm screens the sequence space of a single-chain copolymer efficiently and identifies a wide range of single-molecule structures including extremal radii of gyration, estimating the Pareto front of the structure-space of a binary copolymer as a function of its composition.
