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