Eine supramolekulare Quervernetzung mit überlagerter schneller und langsamer Dynamik wird von Hao Chen, Yi Cao, Yebang Tan et al. im Forschungsartikel auf S. 22506 beschrieben. Diese Quervernetzung weist eine quantitativ maßgeschneiderte Molekulardynamik auf. Die wohldefinierte molekulare Dynamik der Vernetzungen ermöglicht die präzise Kontrolle der Viskoelastizität und des mechanischen Ansprechverhaltens...
Depending on the dynamics of the crosslinks, polymer networks can have distinct bulk mechanical behaviors, from viscous liquids to tough solids. Here, by means of designing a crosslink with variable molecular dynamics, we show the control of viscoelasticity of polymer networks in a broad range quantitatively. The hexanoate‐isoquinoline@cucurbit[7]uril (HIQ@CB[7]) crosslink exhibits in a combination...
