“…PAN‐ co ‐PSSA was synthesized via free radical copolymerization of AN and PSSANa with the feed ratio of AN to SSANa of 10:1, followed by the H + exchange to yield the acid form PAN‐ co ‐PSSA (Scheme ) . This monomer feed ratio was chosen to provide high PSSA content while maintaining water‐insoluble property.…”

Proton conducting membranes based on polymers containing sulfonic acid and tetrazole moieties were developed. Successful syntheses of poly(acrylonitrile-co-styrene sulfonic acid) (PAN-co-PSSA), poly(acrylonitrile-co-5-vinyl tetrazole) (PAN-co-PVTz), and poly(acrylonitrile-co-5-vinyl tetrazole-co-styrene sulfonic acid) (PAN-co-PVTz-co-PSSA) were confirmed by 1 H-nuclear magnetic resonance spectroscopy, elemental analysis, and Fourier transform infrared spectroscopy. Two approaches were performed to study the effects of molar ratio of sulfonic acid to tetrazole and tetrazole content on membrane properties. In the first approach, PAN-co-PSSA was blended with PAN-co-PVTz at three molar ratios. The second approach focused on PAN-co-PVTz-co-PSSA membranes with various tetrazole contents. PAN-co-PSSA membrane was also prepared. All solution-cast membranes were hydrolytically stable, except for PAN-co-PVTz-co-PSSA with 71% tetrazole. Surface morphologies of blend membranes were studied using scanning electron microscopy, and no phase separation was observed. Water uptake was shown to increase with increasing tetrazole. All membranes exhibited high thermal stability (up to 250 8C) and high storage moduli. Proton conductivity was found to depend significantly on relative humidity. The influences of sulfonic acid to tetrazole ratio and tetrazole content on proton conduction were observed and discussed. A maximum proton conductivity of 7.1 3 10 23 S/cm at 26 8C was obtained from PAN-co-PSSA membrane. In addition, all tested membranes showed relatively good oxidative stability after treatment in Fenton's reagent. V C 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 45411.

“… 20,34 Upon grafting PAMPS onto the Si particles, a new band corresponding to the C═O vibration (for PAMPS) appeared at 1636 cm −1 35 . In addition, the intensity of the band at 1003 cm −1 increased, and this could be attributed to the S═O stretching of the SO 3 H groups in PAMPS 34,36,37 …”

Proton conducting membranes based on crosslinked poly(vinyl alcohol) and chitosan were fabricated using sulfosuccinic acid (SSA) and glutaraldehyde (GA) as crosslinking agents. A systematic study on the effects of SSA, chitosan, and GA on membrane properties was conducted. The most promising crosslinked membrane was then chosen to form composites with silica particles containing poly(2‐acrylamido‐2‐methyl‐1‐propanesulfonic acid) (PAMPS‐Si). Two different sizes of PAMPS‐Si with similar PAMPS contents were synthesized from vinyltrimethoxysilane precursor following the Stöber method. The process was followed by free radical polymerization of 2‐acrylamido‐2‐methyl‐1‐propansulfonic acid. Field‐emission scanning electron microscopy, thermogravimetric analysis, and Fourier‐transform infrared spectroscopy techniques were used to analyze the sample. The results revealed the successful synthesis of PAMPS‐Si. All prepared composite membranes exhibited comparable water vapor absorption, water uptake, and ion exchange capacities. The addition of PAMPS‐Si enhanced proton conductivity, and the value increased with increasing loading. The size of the PAMPS‐Si particles did not significantly affect the proton conductivity. These composite membranes demonstrated good thermal and oxidative stabilities.

“…The absorption band at 2242 cm -1 may be attributed to C≡N stretching vibrations [15]. The peak at 762 cm -1 corresponds to S-O stretching vibration and the peaks found at 1169, 1037 and 1009 cm -1 correspond to S=O asymmetric and symmetric stretching vibrations [16,17]. The strong peak of C=O stretching vibration and a 'shoulder' are observed at 1720 and 1618 cm -1 , respectively.…”

The development of proton conductive polyacrylate membranes based on acrylonitrile, sodium 4-vinylbenzenesulfonate, acrylic acid, ethylene glycol dimethacrylate and hybrid polyacrylate/silica membranes is reported in this article. Polyacrylate membranes were synthesized via UV-initiated copolymerization; for the synthesis of polyacrylate/silica membranes 3-methacryloxypropyl trimethoxysilane-based sol–gel system was introduced into the polymerizing mixture.
