Presentation
Atomistic Understanding of the Mechanical Behaviors of Polyamide Ionene Self-Healing Elastomers
Presenter
DescriptionIntrinsic self-healing (SH) polymers can repeatedly heal themselves from mechanical damage by reorganizing their polymer matrices without adding healing reagents. Therefore, they have drawn significant attention to developing sustainable SH soft materials. Recent studies have shown that ion-containing polymers can better harness SH features due to the additional strength of ionic interactions between chains.
In this work, we are mainly interested in supramolecular dynamic chemistry, i.e., non-covalent bonding dynamics, as they can repeatedly heal local damage. Although each non-covalent bond is weaker than its covalent counterparts, together, they can form strong polymer network systems and thus achieve high mechanical strength. Particularly, we are interested in the roles of hydrogen bonding and ionic interaction since they are both dynamic and subject to change upon external stimuli, such as heat or UV light. We will discuss how they affect the structural conformation and thermomechanical properties, as well as their competition with ionic interactions.
