“…And alkyl protons, adjacent protons to N, and heterocycle protons were also observed around 1.0 ppm, 4.0 ppm, and 7.5 ppm, respectively. 25) As for the homopolymer of PS, broad peaks of the alkyl main chain protons (1.0 ppm to 2.5 ppm) and protons attached to the aromatic ring (6.3 ppm to 6.7 ppm and 6.9 ppm to 7.2 ppm) were observed. 26) Therefore, the employed RAFT agent adapted to all the monomers, and RAFT polymers of PVPA, the PIL of P (VPA/1PIm), and PS were successfully synthesized.…”

Polymer electrolyte membrane fuel cells (PEMFC) have the challenges of operation under low humidity conditions caused by the proton conduction mechanism dependent on water. We focused on polymeric ionic liquids (PIL), which are promising for high proton conductivity under the wide range environment because of having the characteristic of the polymer electrolyte liquid. However, it is difficult to fabricate the self-standing membrane of PIL due to the high hygroscopicity and fluidity. In this paper, to inhibit the fluidity of PIL developing the self-standing polymer electrolyte membrane (PEM), the hydrophobic chain segment of styrene is inserted between PIL of poly(vinylphosphonic acid/1-propylimidazole) (P(VPA/1PIm)) by RAFT polymerization. The synthesized sample of P(VPA/1PIm)-block-polystyrene (P(VPA/1PIm)-b-PS) is potentially applicable to PEM materials because it is obtained in a powder state, having the high heat resistance of up 300°C, and performing the proton-conducting property under the wide range environment.

“…The chemical nature of PVI and PVI–Ag was studied by ATR–FTIR spectroscopy. For PVI [Figure A(a)], the N–H stretching vibrations of bisacrylamide cross-linker in the main chain were observed at 3366 and 3250 cm –1 , whereas the presence of aromatic hydrogens bound to the imidazole ring was confirmed by stretching vibrations of CC–H and NC–H at 3150, 3116, and 3100 cm –1 . − The CO stretching vibration appeared at 1744 cm –1 , , whereas the signals at 1640, 1544, 1497, and 1451 cm –1 can be designated to CC stretching vibrations. − …”

Water, the driver of nature, has always been polluted by the blind hurling of highly toxic contaminants, but human-friendly science has continuously been presenting better avenues to help solve these challenging issues. In this connection, the present study introduces novel nanocomposites composed of emulsion-templated hierarchically porous poly(1-vinylimidazole) beads loaded with the silver nanoparticles generated via an in situ approach. These nanocomposites have been thoroughly characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, Brunauer-Emmett-Teller, and field emission scanning electron microscopy. The appropriate surface chemistry, good thermal stability, swelling behavior, porosity, and nanodimensions contributed to achieve very good performance in water treatment. Owing to their easier handling and separation, these novel nanocomposites are highly efficient to remove arsenic and eriochrome black T with decent adsorption capacities in addition to the inactivation and killing of Escherichia coli (Gram-negative) and Staphylococcus aureus (Gram-positive) bacteria.
