Classification of interfacial water governed by water-polymer interactions in hydrated polymers: A molecular dynamics simulation study of ethylene-based and acrylate polymers

Atsuki Hashimoto, Kang Kim, Kokoro Shikata, Nobuyuki Matubayasi

Molecular dynamics simulations classify seven polymers into three hydration types based on water-polymer interactions.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

These results clarify three hydration types: highly hydrated (PVA, PHEA, and PHEMA), hydrophobic (PMEMA and PBA), and flexibly hydrated (PEG and PMEA), and provide a molecular-level framework for interpreting interfacial water governed by water-polymer interactions.

C2weakest assumption

The classification and dynamical distinctions rest on the assumption that the chosen molecular dynamics force fields and simulation protocols accurately reproduce the real hydrogen-bond lifetimes, chain fluctuations, and water localization in these polymers.

C3one line summary

MD simulations classify hydrated polymers into highly hydrated, hydrophobic, and flexibly hydrated types using Tg dependence, chain fluctuations, HB lifetimes, and van Hove functions.
