“…The polymer membranes based on acid-doped triazole functional polymers would be interesting where high conductivity can be obtained even at lower dopant ratios [10,11]. The presence of three nitrogens in the ring may enhance long range proton diffusion, which can be far better than imidazole based host polymer, i.e., poly(4(5)-vinyl-imidazole) [12].…”

a b s t r a c tPolymer electrolyte composite membranes based on poly(1-vinyl-1,2,4-triazole) (PVTRI) and nitrilotri(methyl triphosphonic acid) (TPA) were investigated. PVTRI was produced by free radical polymerization of 1-vinyl-1,2,4-triazole. The polymer PVTRI was doped with TPA at various molar ratios x ¼ 0.125, x ¼ 0.25, and x ¼ 0.5. The proton transfer from TPA to the triazole rings was proved with Fourier-transform infrared spectroscopy (FT-IR). Thermogravimetry (TG) analysis showed that the samples are thermally stable up to approximately 250 1C. DSC results illustrated the homogeneity of the materials as well as the softening effect of the dopant. Cyclic voltammetry results illustrated that the electrochemical stability domain of the dopant extends over 1.5 V. The maximum proton conductivity has been measured for PVTRITPA-0.25 as 8.5 Â 10 À 4 S cm À 1 at 150 1C.

“…The second loss between 140 and 380°C was related to the losses of sulphonic acid pendants of PSSA-MA and PVA main and side chains. The third loss above 380°C corresponded to the loss of PSSA-MA main chain [31][32][33] . A gradual increase in weight residue with increasing PSSA-MA suggested the increase in degree of crosslinking.…”

Electrospun fibres from polyvinyl alcohol (PVA), poly(styrene sulphonic acid-co-maleic acid) (PSSA-MA), and imidazole for potential use as proton conducting membranes at elevated temperatures were prepared and characterized. The effect of PSSA-MA content (9,17,25,33, 42, and 50% by weight of PVA) on solution properties was investigated. Fibre mats were obtained from solutions with 9-33% PSSA-MA. Solution viscosity increased with increasing PSSA-MA until reaching a maximum at 33% PSSA-MA. The effect of PSSA-MA content on fibre size and morphology was studied using scanning electron microscopy. Fibre diameter was found to increase with increasing solution viscosity. A solution with 25% PSSA-MA provided uniform and bead-free fibres with an average diameter of 485 nm. Thermal crosslinking of electrospun fibres was confirmed by attenuated total reflection Fourier transform infrared spectroscopy and thermogravimetric analysis. Electrospun fibres were thermally stable up to 250°C. Fibres containing 25% PSSA-MA had a proton conductivity in nonhumidified conditions comparable to that of a solvent-cast membrane with the same composition. The proton conductivity of a solvent-cast membrane was slightly higher than that of fibres over the temperature range studied.

The CuAAC “click” reaction has developed as one of the most useful and widely employed reactions in ligation within polymer chemistry. This is due to the unique properties of the Cu(I) catalysis which renders the reaction quantitative even at low concentrations, orthogonal with other chemistries and extremely robust. The formed triazole on the other hand is of intermediate polarity and chemically and biochemically “invisible”, and the CuAAC provides the ideal “click” reaction for stitching together polymer architectures of unprecedended complexity as was it molecular LEGO. The CuAAC “clicking” in polymer chemistry is increasing exponentially and lead to highly defined polymer materials with novel properties.magnified image
