Therefore, they nonetheless contributed to proton conduction w cross-link websites using the sulfonic acid groups in the sulfonated polymer [42]. The advantage cross-link internet sites together with the sulfonic acid groups from the sulfonated polymer [42]. The adblend, in contrast towards the ionic cross-links among PBI along with the sulfonated polyme of the PSU-Py is its exceptionally low basicity (the pKa of thepKa on the protonated pyridine-N vantage on the PSU-Py is its very low basicity (the protonated pyridine-N calculated the proton was localized which leads to incredibly “loose” ionic it the protons have been by ACD is two.7+/-0.1), 2.7+/-0.1), near the imidazole-N. Thus,cross-links. Here, the imm calculated by ACD is which leads to pretty “loose” ionic cross-links. Here, was drastically which is indicated by mobile and anticipated to not be completely “captured” within nonetheless somewhat mobile and expected to not be in PBI/sulfonated polymers’ acid ase blen protons were still somewhat the truth that completely “captured” inside the ionic crosslinks. For that reason, they Consequently, they still contributed to proton conduction in contrast the ionic cross-links. nonetheless contributed to proton conduction within the blend, within the branes, the calculated ion-exchange capacities had been quite close to the measured o to the ionic cross-links involving PBI andbetween PBI plus the sulfonated polymer, exactly where blend, in contrast topreparation procedures with the sulfonated polymer from bispheno In PF-05105679 web Figure two, the the ionic cross-links the sulfonated polymer, where the proton was localized close to the imidazole-N.
