Polymer gels can be effectively applied to plug fractured reservoirs and carbonate cave strata. Herein, polyvinyl alcohol (PVA), acrylamide, and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) were used as raw materials to prepare interpenetrating three-dimensional network polymer gels using formation saltwater in the Tahe oilfield (Tarim Basin, NW China) as a solvent. The effect of AMPS concentration on the gelation properties of PVA in high-temperature formation saltwater was analyzed. Further, the effect of PVA concentration on the strength and viscoelastic properties of polymer gel was studied. The polymer gel could retain stable continuous entanglement at 130 °C and exhibited satisfactory thermal stability. Continuous step oscillation frequency tests showed that it exhibited an excellent self-healing performance. Scanning electron microscopy images of the simulated core by gel plugging showed that the polymer gel could firmly fill the porous media, indicating that the polymer gel exhibits excellent application prospects in oil and gas reservoirs under high-temperature and high-salinity conditions.

The pollution and scarcity of freshwater resources are global problems that have a significant influence on human life. It is very important to remove harmful substances in the water to realize the recycling of water resources. Hydrogels have recently attracted attention due to their special three-dimensional network structure, large surface area, and pores, which show great potential for the removal of pollutants in water. In their preparation, natural polymers are one of the preferred materials because of their wide availability, low cost, and easy thermal degradation. However, when it is directly used for adsorption, its performance is unsatisfactory, so it usually needs to be modified in the preparation process. This paper reviews the modification and adsorption properties of polysaccharide-based natural polymer hydrogels, such as cellulose, chitosan, starch, and sodium alginate, and discusses the effects of their types and structures on performance and recent technological advances.

“…The most popular subjects in recent times are the loading of these fertilizers into hydrogels, a polymeric material, by the sorption method and their use as a controlled release system [12][13][14]. Indeed, hydrogels are crosslinked polymeric network structures that have the ability to swell by absorbing water into their dry masses, thanks to the hydrophilic functional groups in polymer chains [15][16][17]. Also, hydrogels can respond to environmental changes such as ionic strength, pH, temperature and magnetic and electric fields [18].…”

To reduce water pollution caused by fertilizers in agricultural irrigation, highly swelling crosslinked hydrogels (p(DMAAm-co-MA) or DM 1 ) based on N,Ndimethylacrylamide (DMAAm) and maleic acid (MA) were prepared using a chemical initiator with the redox polymerization technique. Negative and positive surface modifications of DM 1 were achieved using hydrochloric acid (HCl) (p(DMAAm-co-MA)/HCl or DM 2 ) and sodium hydroxide (NaOH) (p(DMAAm-co-MA)/NaOH or DM 3 ), respectively. The synthesized hydrogels were named DM 1 , DM 2 and DM 3 , respectively. The swelling properties, urea sorption and urea release kinetics of synthesized hydrogels were analyzed in deionized water at different pHs. The sorption isotherms and sorption parameters were investigated thoroughly for all hydrogels and the Langmuir (L) isotherm showed the best fit. In order to examine the urea release mechanism from all hydrogels, four mathematical models of zero-order kinetic model (Z-O), first-order kinetic model (F-O), Higuchi (H) and the Korsmeyer-Peppas power law (K-P) were studied to fit the experimental data. The hydrogels exhibited swelling and releasing properties that were highly dependent on their functional groups and the ionic forces in the medium. Cumulative urea release values for DM 1 , DM 2 and DM 3 were calculated as 100% at pH 10, 100% at pH 8 and 100% at pH 8 within 48, 41 and 18 h, respectively. It was confirmed by experimental studies that the prepared hydrogels and their derivatives can be used as carriers for fertilizers, particularly urea, as well as controlled water release sources. As a result, the use of the synthesized hydrogels to prevent contamination of water resources with agricultural products and to provide a nitrogen source that plants require comprise the innovative and original aspect of the article.
