MXene Crosslinked Hydrogels with Low Hysteresis Conferred by Sliding Tangle Island Strategy

Small, Journal Year: 2024, Volume and Issue: 20(35)

Published: April 29, 2024

Single-network hydrogels are often too fragile to withstand mechanical loading, whereas double-network typically exhibit significant hysteresis during cyclic stretching-releasing process due the presence of a sacrificial network. Consequently, it is considerable challenge for designing that both low in and high toughness applications requiring dynamic loads. Herein, study introduced novel "sliding tangle island" strategy creating tough low-hysteresis hydrogels, which prepared through situ polymerization highly concentrated acrylamides (AM) form numerous entanglements within MXene spacing without any chemical crosslinker. The entangled with long polyacrylamide (PAM) chains island served as relay station transmit stress neighboring molecular chains. This mechanism helps alleviate concentration enhances energy dissipation efficiency, thereby reducing hysteresis. resulting hydrogel exhibited exceptional properties, including stretchability (≈900%), (less than 7%), (1.34 MJ m
