Existence of a Glassy Layer in the Polymer‐Nanosheet Interface: Evidence from Molecular Dynamics

The interfacial polymer‐nanosheet behavior is investigated to fully understand the interfacial interaction mechanism. The emphasis is placed on the discussion whether a “polymer glassy layer” in the proximity of the nanosheet exists or not. Results indicate that a “polymer glassy layer” actually exists near the nanosheet surface for strongly attractive interfacial interaction. Moreover, the glass transition temperatures at different interfacial interactions are explored, and a gradient of polymer chain dynamics near the nanosheet surface is observed. In short, this work provides a valuable reference for understanding polymer‐nanosheet interfacial behavior.
