To demonstrate the improved properties of the polyacrylamide hydrogel and its suitability for use in the oil industry, several testing methods were applied. Characterisation of the 2-(hexadecyloxy) ethyl methacrylate surfmer was performed using thermogravimetric analysis (TGA), which evaluated the decomposition profile of the hydrogel sample while proton nuclear magnetic resonance (1H-NMR) was conducted to confirm the complete polymerisation of the monomers along with the absence of different chemical shifts. This indicated that the SPH materials exhibit reasonable gel strength and stability. The application of superabsorbent polymer hydrogels is gaining much research attention.

It is occasionally sold as "water gel powder," "slush powder," or "instant solid powder." The third stage of decomposition is attributed to depolymerisation reactions and the breaking of the crosslinks between the different polymeric chains. In summary, up to date studies have investigated the effects of hydrogel composition (mainlymonomer,crosslinker, and initiator concentrations) and operating conditions such as temperature, salinity and pH on hydrogel strength andswelling performance. quantity 10, the swelling behaviour of the poly (acrylamide-co-acrylic acid) potassium salt and sodium acrylate typically demonstrate maximum swelling between pH 6.5 (neutral medium) and 9 after free swelling at 25C for 2-, 4- and 6-h.

Sensitivity of the polymer under varying conditions shows that it exhibits maximum swelling capacity of 1700% in neutral medium at 50C after 15h. The study concluded that this class of superabsorbent has potential applications for water absorption purposes. Under the same optical condition, an image of a linear scale was used for calibration. The difference in mobile ion concentration between the polymer networks and liquid phases decreases resulting in a decrease in absorbency capacity. Sodium polyacrylate can absorb a huge amount of water compared to most other materials. You can use material from Hydrogel of poly(acrylamide-co-sodium acrylate) may be used to remove water from liquid fuels.

Their hydrophilic functional groups are responsible for their superabsorbent nature which does not lead to dissolution but rather result in formation of an insoluble gel. It is widely used as waterproof material for the exterior of cables and water-blocking material for lightweight flood-proof sandbags. Findings on the morphologies of the materials showed irregular surfaces which is suggested to cause high swelling ratios due to the diffusion of water through the surface. The difference in pore size distribution may explain the difference in swelling performances of the two polymers. [25] and Alonso et al. It is widely used as waterproof material for the exterior of cables and water-blocking material for lightweight flood-proof sandbags. Finally, they compared the swelling behaviour of the hydrogels under different conditions.

High temperature stability is an important property for medium- to high-temperature industrial processes because many of the organic polymers commonly used thermally decompose above 120C [36]. In neutral aqueous activation fluids, the concentration of moveable ions (\( C_{i}^{s} \)) is very small, which is responsible for the higher value of \( \pi_{ion} \).
