A Short Review on the N,N-Dimethylacrylamide-Based Hydrogels

Abstract

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.

Transparent ionic conductive elastomers with high mechanical strength and strong tensile properties for strain sensors

“…49,50 In addition, hydrophobic interactions, hydrogen bonds and ionic dipole interactions in the N , N -dimethyl acrylamide structures can also enhance the mechanical strength of elastomers. 51 Considering the conductivity and other mechanical properties of PDES–DMA elastomers, we selected the PDES–DMA elastomer prepared with a molar ratio of PDES to DMA of 4 : 1 (toughness 55.5 MJ m −3 , Young's modulus 0.4 MPa) (Fig. 3c) for subsequent performance tests.…”

Can Supramolecular Polymers Become Another Material Choice for Polymer Flooding to Enhance Oil Recovery?

“…It is found that the introduction of hydrolysis groups makes the polymer transform into polyelectrolyte, which is helpful to the extension of the molecular chain, and at the same time, it avoids a large amount of adsorption on the surface in the formation pores. The rheological properties of HPAM are greatly affected by the formation environment, so other synthetic polymers have also been applied to enhance oil recovery, including branched poly (propylene amide) [ 50 ], N, N-dimethylacrylamide copolymer [ 51 ], and HPAM derivatives with temperature and salt-resistant monomers (such as AMPS and NVP) [ 52 , 53 , 54 ]. No matter whether HPAM or other synthetic polymers, the polymer molecular chain has the characteristics of flexibility, easy change of molecular conformation, and extremely easy to bend and entangle.…”

Semi-Synthetic Click-Gelatin Hydrogels as Tunable Platforms for 3D Cancer Cell Culture

“…The limitations demonstrated by BME matrices have led to the development of alternative 3D cell culture platforms, which aim to address these limitations. For example, hydrogels are water-swollen polymeric networks, formed through the interaction of hydrogel precursors, that can provide suitable environments for 3D cell culture [ 22 , 23 ]. Poly(ethylene)-glycol (PEG)-based hydrogels are synthetic 3D cell culture matrices, produced through crosslinking of PEG-based hydrogel precursors [ 16 , 21 , 24 , 25 ] that can be produced with high batch-to-batch reproducibility, therefore addressing the cross-batch variability observed in BME matrices.…”
