Branched sulfonated polyimide (bSPI) membranes based on three different non-sulfonated diamine monomers were fabricated for vanadium redox flow battery (VRFB) usage. Both FT-IR and 1H NMR spectra confirm that bSPIs were successfully synthesized. TGA results show that bSPI membranes have good thermal stability. FESEM pictures indicate that the surface of membrane in contact with catholyte keeps better...
Low-cost branched sulfonated polyimide (bSPI) membranes were prepared for vanadium redox flow battery (VRB) application. The degree of branching (DB) of membranes was controlled to be 0–12% through changing the mole ratio of branched non-sulfonated diamine to dianhydride. Both FT-IR and NMR spectra verified the successful preparation of bSPI membranes. The morphology was observed using SEM. Thermal...
