“…Additional absorptions at 1040 and 1180 cm −1 correspond to symmetric and asymmetric vibration absorption of SO 3 − groups, respectively [48]. Absorption at 1615 cm −1 confirmed carbonyl stretching absorption by amide functionality present in the copolymer corresponding to the poly (DMA) segment [42,49]. The characteristic C-H bond from poly(DMA) units at around 2920 cm −1 was observed for vibration due to CH 3 groups along with the band around 1500-1570 cm −1 corresponds to C-N bending.…”

“…The super-adsorbent hydrogel was prepared using a free radical polymerization technique in aqueous solution using a closed kettle reactor assembly as per our previously reported procedure [42]. A typical polymerization process is as follows: a GelMA solution (1% w/v) was prepared in 75 mL deionized water to which NaSS (13.5 g, 60 mol-% of total monomer) and DMA (4.34 g, 40 mol-% of total monomer) were added under argon gas and stirred until clear solution was obtained.…”

Removal of dyes through adsorption from wastewater has gained substantial interest in recent years, especially in development of hydrogel based adsorbents, owing to their easy use and economical nature. The aim of the present study was to design a super-adsorbent hydrogel based on sodium styrenesulfonate (NaSS) monomer for removal of dyes like methylene blue (MB). NaSS displays both an aromatic ring and strongly ionic group in its monomer structure that can enhance adsorption capacity. Poly(sodium styrenesulfonate-co-dimethylacrylamide) hydrogels were prepared by solution free radical polymerization using gelatin methacryloyl (GelMA) as crosslinker, creating a highly porous, three-dimensionally crosslinked polymer network contributing to higher swelling ratios of up to 27,500%. These super-adsorbent hydrogels exhibited high adsorption capacity of 1270 mg/g for MB adsorption with above 98% removal efficiency. This is the first report for such a high adsorption capacity for dye absorbance for NaSS-based hydrogels. Additionally, the adsorption kinetics using a pseudo-first-order and the Freundlich adsorption isotherm models for multilayer, heterogeneous adsorption processes has been reported. The adsorbents’ reusability was confirmed through 4 repeated cycles of desorption-adsorption. The results discussed herein illustrate that NaSS based chemistries can be used as an efficient option for removal of organic dyes from contaminated wastewater.

“…The swelling ratio of the fiber in DI water significantly increased under high temperature (Figure S12b). The increase in the swelling ratio of the fiber indicates that the larger amount of reducing agent solution can be absorbed into the fiber under high temperature during the reduction step. , Therefore, more Ag precursors can be reduced to AgNPs in the fiber matrix under high temperature, forming more dense connections between AgNPs in the fiber sensor. Figures a and S12a show the initial electrical resistances of the fiber strain sensors fabricated by the reduction step under high temperatures.…”

Wearable electronic devices have attracted significant attention as important components in several applications. Among various wearable electronic devices, interest in textile electronic devices is increasing because of their high deformability and portability in daily life. To develop textile electronic devices, fiber-based electronic devices should be fundamentally studied. Here, we report a stretchable and sensitive fiber strain sensor fabricated using only harmless materials during an in situ formation process. Despite using a mild and harmless reducing agent instead of typical strong and hazardous reducing agents, the developed fiber strain sensors feature a low initial electrical resistance of 0.9 Ω/cm, a wide strain sensing range (220%), high sensitivity (∼5.8 × 10 4 ), negligible hysteresis, and high stability against repeated stretching−releasing deformation (5000 cycles). By applying the fiber sensors to various textiles, we demonstrate that the smart textile system can monitor various gestures in real-time and help users maintain accurate posture during exercise. These results will provide meaningful insights into the development of next-generation wearable applications.

“…Polymer Systems: Polyacrylamide is a common synthetic polymer system that has been widely studied and applied [ 64 ]. A recent study reported that more than 85% reduction in viscosity was observed when polyacrylamide was aged at 130 °C for three months [ 90 ]. This implies that any polyacrylamide-based system applied for high-temperature applications is suspectable to thermal degradation with time.…”

Conformance problems often exist in natural gas-related activities, resulting in excessive water production from natural gas production wells and/or excessive natural gas production from oil production wells. Several mechanical and chemical solutions were reported in the literature to mitigate the conformance problems. Among the chemical solutions, two classes of materials, namely polymer gels and water-soluble polymers, have been mostly reported. These systems have been mainly reviewed in several studies for their applications as water shutoff treatments for oil production wells. Natural gas production wells exhibit different characteristics and have different properties which could impact the performance of the chemical solutions. However, there has not been any work done on reviewing the applications of these systems for the challenging natural gas-related shutoff treatments. This study provides a comprehensive review of the laboratory evaluation and field applications of these systems used for water control in natural gas production wells and gas shutoff in oil production wells, respectively. The first part of the paper reviews the in-situ polymer gel systems, where both organically and inorganically crosslinked systems are discussed. The second part presents the water-soluble polymers with a focus on their disproportionate permeability reduction feature for controlling water in gas production wells. The review paper provides insights into the reservoir conditions, treatment design and intervention, and the success rate of the systems applied. Furthermore, the outcomes of the paper will provide knowledge regarding the limitations of the existing technologies, current challenges, and potential paths forwards.
