Influence of crystal morphology of 1H-1,2,4-triazole on anhydrous state proton conductivity of sulfonated bisphenol A polyetherimide based polyelectrolytes

Proton Conducting Copolymer Electrolytes Based on Vinyl Phosphonic Acid and 5‐(Methacrylamido)tetrazole

“…N ‐heterocyclic molecules have been widely used for the production of anhydrous proton‐conducting membranes . Majority of the heterocyclic groups such as imidazole, benzimidazole, triazole, and tetrazole have high boiling points, which make them attractive for the synthesis of more temperature‐tolerant, proton‐conductive membranes that can be applicable to various electrochemical devices such as fuel cells at elevated temperatures …”

“…N -heterocyclic molecules have been widely used for the production of anhydrous protonconducting membranes. [ 3 ] Majority of the heterocyclic groups such as imidazole, [ 4 ] benzimidazole, [ 5 ] triazole, [6][7][8][9][10] and tetrazole [ 11,12 ] have high boiling points, which make them attractive for the synthesis of more temperaturetolerant, proton-conductive membranes that can be applicable to various electrochemical devices such as fuel cells at elevated temperatures. [ 13,14 ] Quite recently, phosphoric acid (H 3 PO 4 )-doped polybenzimidazoles (PBIs) were reported as promising electrolyte candidates for high-temperature PEMFCs, with high performance.…”

Synthesis and application of cotton‐based chelate fibers grafted with poly(1‐vinyl‐1,2,4‐triazole) side chains

“…The infrared spectra of the untreated cotton fibers and the cotton‐ g ‐PVTAZ fibers are shown in Figure . The effect of graft on the absorption bands of cotton fibers can be summarized as follows: the triazole rings of the cotton‐ g ‐PVTAZ give rise to several medium or strong peaks, e.g., the characteristic peaks in the 1430–1650 cm −1 range are due to ring stretching (CC/CN) vibrations, the characteristic peak at 1270 cm −1 is due to the ring stretching (NN) vibrations, and the characteristic peak at 3120 cm −1 is due to the ring stretching (CCH/NCH) vibrations . The appearance of these characteristic peaks indicated that triazole‐based groups were successfully grafted onto the cotton fibers.…”

Synthesis and proton conductivity studies of methacrylate/methacrylamide‐based azole functional novel polymer electrolytes

“…A common technique used in the synthesis of anhydrous proton conducting materials is the doping of the polymer matrix with heterogenic compounds such as imidazole, benzimidazole, and triazole . Since these azole groups have high melting points (100–200 ° C), they successfully substituted water and provided high proton conductivity.…”
