Dynamic covalent bond-based hydrogels with superior compressive strength, exceptional slice-resistance and self-healing properties

Abstract

A novel dynamic-covalent bond-based single network hydrogel was developed, of which the failure compressive stress and strain as well as the failure tensile stress and strain could exceed 27.3 MPa and 98.4% as well as 0.23 MPa and 282.3%, respectively. In addition, the gel shows remarkable slice-resistance and self-healing properties.
