Synthesis and characterization of sulfonated polyimides derived from 2,2′-bis(4-sulfophenyl)-4,4′-oxydianiline as polymer electrolyte membranes for fuel cell applications

Synthesis and characterization of novel anion exchange membranes based on imidazolium-type ionic liquid for alkaline fuel cells

“…It is essential to improve the interface between the electrode and AEM electrolyte [23]. The solubility behaviors of the membranes in some selected solvents were studied and the results were presented in Table 2.…”

Comparative Kinetic Study and Microwaves Non-Thermal Effects on the Formation of Poly(amic acid) 4,4′-(Hexafluoroisopropylidene)diphthalic Anhydride (6FDA) and 4,4′-(Hexafluoroisopropylidene)bis(p-phenyleneoxy)dianiline (BAPHF). Reaction Activated by Microwave, Ultrasound and Conventional Heating

“…Polyimides have been used in nanofiltration [1], hydrogen purification [2], fuel cells [3], adhesive [4], and solar cells [5]. …”

Side-chain sulfonated random and multiblock poly(ether sulfone)s for PEM applications

“…CO), both allowing the use of less amounts of catalysts, and (c) water management is much easier due to the absence of liquid water [1]. Nowadays research in materials for ion-exchange membranes is focused on sulfonated fully aromatic polymers such as polyimides [2][3][4][5], poly(ether sulfone)s, polysulfones, poly(ether ether ketone)s (for sulfonated poly(arylene ether)s see for example the review [6] and references therein), or recently, poly(phenylene sulfone)s [7][8][9]. The sulfonic acid group can be introduced into the polymer chain either by the use of already sulfonated monomers or by a post-sulfonation step.…”
