“…Weng et al modified natural polysaccharides with DMAA and obtained highly porous hydrogels with high mechanical strength. Even though the obtained hydrogel contained more than 90% water, it still withstood high compressive strength [ 57 , 58 , 59 ]. Furthermore, in Figure 5 , hydrogels with and without the addition of DMAA were demonstrated.…”

Scientists have been encouraged to find different methods for removing harmful heavy metal ions and dyes from bodies of water. The adsorption technique offers promising outcomes for heavy metal ion removal and is simple to run on a large scale, making it appropriate for practical applications. Many adsorbent hydrogels have been developed and reported, comprising N,N-dimethylacrylamide (DMAA)-based hydrogels, which have attracted a lot of interest due to their reusability, simplicity of synthesis, and processing. DMAA hydrogels are also a suitable choice for self-healing materials and materials with good mechanical properties. This review work discusses the recent studies of DMAA-based hydrogels such as hydrogels for dye removal and the removal of hazardous heavy metal ions from water. Furthermore, there are also references about their conduct for self-healing materials and for enhancing mechanical properties.

“…8,9 However, their poor mechanical properties often restrict their practical applications which require high mechanical strength and large deformation recoverability. 10 In order to toughen these gels, multi-networks, 11,12 phase-separation, 13 ion bonding 14 and nanoparticles 15 are incorporated into them to increase energy dissipation during deformation, thus enhancing their toughness. However, these network structures are easily damaged, which results in the rupture of the gels.…”

“…Although their reversible covalent and ionic bonds have been widely employed to generate self-healing effects, 2,6,14 the reconstruction of network structures is usually time-consuming, thus leading to a serious deterioration in their mechanical strength when the gels undergo continuous and multiple loading–unloading cycles. 10,16 Therefore, it is critically required to toughen these gels in order to withstand the repeated deformation and achieve good stretchability and recoverability.…”
