•Triphenylamine containing sulfonated polyimides (SPIs) were synthesized.•SPIs showed high proton conductivities (up to 207mScm−1 at 80°C in water).•Good phase-separated morphology and low fuel crossover was observed for these SPIs.
A series of new sulfonated co-polyimides (co-SPI) were prepared by the polycondensation reaction of two diamines namely; 4,4′-diaminostilbene-2,2′-disulfonic acid (DSDSA) and 4,4′-diaminotriphenylamine (DATPA) with 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTDA). All the copolymers showed good solubility and flexible membranes were obtained from their DMAc solution. The transmission electron microscopy (TEM) of the polymers revealed microphase separated morphology with well-dispersed hydrophilic (around 5–100nm) and hydrophobic domains. The SPI membrane DTN-80 (80% degree of sulfonation) with ionic exchange capacity (IECw) of 2.74mequivg−1 showed significantly higher proton conductivity (207mScm−1) at 80°C in water as compared to the perfluorinated Nafion® 117 (135mScm−1) under similar test conditions. All these co-SPI membranes showed lower oxygen permeability (for DTN-80, PO2=0.9barrer) than Nafion® 117 (PO2=3.6barrer). |
