ABSTRACT Metal ion‐assisted hydrogels are of growing interest because their excellent mechanical properties, fast recovery, and self‐healing ability. However, affording all these properties in a single polymeric framework is very challenging. This paper presents facile one‐pot synthesis Zn 2+ coordinated by using acrylic acid acrylamide monomer as precursors. Special emphasis has been placed on the types zinc salt that have not studied before. Zinc coordination provides hydrogel with prominent strength, toughness, stretchability, without any stimulation, due to numerous entanglements chains. Rheology studies demonstrate various salts used for functional groups could influence gels different extents. The highest potential exhibited MGel‐ZnCl 2 (up 90% recovery) while those MGel, MGel‐Zn(NO 3 ) , MGel‐ZnSO 4 60%, 62%, 64%, respectively. Dynamic analysis reveals higher compressive strength (0.86 MPa) when compared other samples viz. MGel (0.48 MPa), (0.49 (0.45). On hand, offers remarkable strain stability at ε % = 66.63 surpassing ( 11.05), 55), 17).
