“…In recent studies, DMAA hydrogel nanocomposites have been used as adsorbents to remove heavy metals from wastewater. Some studies reported that DMAA hydrogels are best for removing gold ions, because their amine groups are very active for Au(III) ions [ 40 , 41 ]. On the other hand, at high pH, amine groups acting as a base increase the binding potentials of heavy metal cations due to the electrostatic attraction of the ions, thus improving the removing efficiency of heavy metal ions ( Figure 3 b) [ 42 , 43 ].…”

“…Tokuyama et al prepared highly crosslinked DMAA gel, which was composed by DMAA/MBAA = 750/30 mol/m 3 , N,N-methylenebisacrylamide (MBA) as cross-linker (30 mol/m 3 ), N,N,N,N-tetramethylethylenediamine as catalyzer (5 mol/m 3 ), and ammonium peroxodisulfate (APS) (0.5 mol/m 3 ) as initiator. The reaction was carried out at 5 °C under nitrogen atmosphere for 24 h. The resulted hydrogel was used for AU(III) ions detection [ 40 ]. A XG-cl-DMAA/SiO 2 hydrogel nanocomposite was synthesized by using MBA as the cross-linker and APS as the initiator in a domestic microwave.…”

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.

The present review presents the most recent developments concerning the application of sensory polymers in the detection and quantification of different target species. We will firstly describe the main polymers that are being employed as sensory polymers, including, for example, conducting or acrylate-based polymers. In the second part of the review, we will briefly describe the different mechanisms of detection and the target species, such as metal cations and anions, explosives, and biological and biomedical substances. To conclude, we will describe the advancements in recent years concerning the fabrication of micro and nano sensory devices based on smart polymers, with a bibliographic revision of the research work published between 2005 and today, with special emphasis on research work presented since 2010. A final section exposing the perspectives and challenges of this interesting research line will end the present review article.

The kinetics of copolymerization is one of the key factors for optimization the process in large scale of production. Copolymerization of N, N‐dimethyl‐N,N‐diallyammonium chloride (DMDAAC) with N,N‐dimethyl acrylamide (DMAA) was studied by a dilatometer technique using ammonium persulfate ([NH4]2S2O8) as an initiator. The effect of the parameters (including molar ratio of DMDAAC to DMAA, concentrations of monomers [M] and initiator [I], and the temperature) on the polymerization rate was analyzed. From these analyses it was found that the polymerization rate (Rp) with the above variables can be represented as the following relationship: Rp∝ [M]2.63; Rp∝ [I]0.40 andRp∝[MDMDAAC:MDMAA]‐0,86.The negative order found in the relationship of the reaction rate and the monomer composition indicated that the DMDAAC concentration in the monomers composition conversely affected the polymerization rate. The overall activation energy for the polymerization rate was 39.56 kJ/mol in the temperature range between 40°C and 60°C. Based on the experimental results, the mechanism of polymerization is discussed in detail. Different thermal properties for DMDAAC and DMDAAC‐DMAA were observed by differential scanning calorimetry (DSC), and thermogravimetry (TG) analysis. Addition of DMAA to DMDAAC lowered the thermal stability relative to the home polymer of DMDAAC.
