Different polyvinyl acetate ratios were mixed with acrylamide and nanoparticle ferric chloride and then exposed to varying doses of gamma irradiation. The optimal gamma irradiation dose for achieving final cross-linking and obtaining a superabsorbent hydrogel was determined to be 20 kGy. The hydrogel was foamed to create a three-dimensional structure to enhance groundwater decontamination efficiency. The resulting polymer was chemically, thermally, and morphologically characterized. The porosity was evaluated using the Brunauer, Emmett, and Teller method (BET) and Positron Annihilation Lifetime Spectroscopy (PALS). The foam exhibited significantly greater water swelling compared to the hydrogel with the same composition, increasing it by a factor of 4,818. When comparing the foam, hydrogel, and commercially available poly electrolytes (polyacrylamide) in terms of electric conductivity (EC), ion exchange capacity (IEC), and hardness, the foam displayed exceptional fantastic properties. Many groundwater patterns were studied, such as turbidity, pH, total dissolved solids (TDS), chemical oxygen demand (COD), biological oxygen demand (BOD), turbidity bacterial cells’ disinfection, and rotavirus.

“…Therefore, polymer graft modifica-tion has become a simple and effective method to expand the scope of polymer application and improve the material properties. Abdel-Hady [35] grafted a binary monomer (styrene and vinyl pyrrolidone) onto an ECTFE membrane with different gamma radiation doses. When the ratio of styrene to vinyl pyrrolidone was 1:1, the applicability of a proton exchange membrane fuel cell (PEMFC) was explored by its ion exchange performance, water absorption energy, proton conductivity, free volume size, membrane thickness, and tensile strength.…”

“…The anode is the negative terminal of the power source and the cathode is the positive terminal of the power source. According to the principle of fuel cells, the membrane must have a good proton conductivity, high dielectric constant, low methanol and gas permeability, high chemical equilibrium, and mechanical properties [35]. Abdel-Hamed [39] used a solution-grafting technique to graft styrene onto commercial ECTFE membranes and then sulfonated the membranes.…”

Ethylene-chlorotrifluoroethylene (ECTFE) was first commercialized by DuPont in 1974. Its unique chemical structure gives it high heat resistance, mechanical strength, and corrosion resistance. But also due to these properties, it is difficult to prepare a membrane from it by the nonsolvent-induced phase separation (NIPS) method. However, it can be prepared as a microfiltration membrane using the thermally induced phase separation (TIPS) method at certain temperatures and with the selection of suitable solvents, and the use of green solvents is receiving increasing attention from researchers. The surface wettability of ECTFE membranes usually needs to be modified before use to strengthen its performance to meet the application requirements, usually by graft modification and surface oxidation techniques. This paper provides an overview of the structure of ECTFE and its preparation and modification methods, as well as recent advances in its application areas and prospects for the future methods of preparing high-performance ECTFE membranes.
