A simple method is reported for the preparation of selfassembling sulfonated graphene oxide membranes (SGO-X) to be studied as a potential proton conductor for proton exchange membrane fuel cells (PEMFCs). The effect of three different sulfuric acid-to-GO molar ratios is investigated, the main aim being the identification of an optimal sulfonation interval ensuring a successful trade-off among composition, structural stability and functional properties. ATR-FTIR and EDX spectroscopies, SEM, thermogravimetry and static contact angle measurements allow to analyze the efficacy of the functionalization of graphene oxide (GO) with sulfonic acid groups (-SO3H) and the uniformity of the component's structure. A preliminary examination of the proton conductivity is performed on the most promising samples (SGO-1, SGO-20) by means of electrochemical impedance spectroscopy (EIS), together with the evaluation of water uptake, ion exchange capacity and degree of sulfonation. This introductory work demonstrates that the proposed SGO-X membranes exhibit notable water-retaining and proton-exchanging properties at elevated temperatures and reduced humidity, compared to pristine GO and Nafion® 212 benchmark specimens. Therefore, these innovative self-standing materials are proved to be worthy of additional studies for the optimization of their features, foreseeing the assessment of their behavior as a possible electrolyte in a PEM fuel cell.

“…In addition to incorporating the PI component into different matrices, PI itself can be fabricated as a freestanding matrix to form a composite with other materials. To date, various PI nanofiber mats have been fabricated by the electrospinning technique [73]. Because PI nonwovens are usually prepared with rather low mechanical properties because of the weak interaction between PI fibers, polymers with low melting temperatures are incorporated to fuse nanofibers and therefore enhance the separator's tensile strength [74].…”

“…The electrospun and non-woven membranes were randomly overlaid layer-by-layer, and no beads existed microscopically in the fibers. The presence of beaded fibers is an important problem in the electrospun Nano fibrous membrane separator, which can negatively affect the lucrative properties of the electrospun Nano fibrous membranes [36].

“…Viscosity is a momentous parameter which plays a key role in changing the fiber size [37]. The diameter of the average fibers was controlled by regulating the concentrations of polymers and electrospinning parameters [36]. Enhancement in the amount of PVA and MA polar materials in the PAN solution resulted in substantial improvement in the viscosity of the solution and consequently the diameter of the fibers [38,39].…”

The present study aimed to investigate the mechanical, thermal, and electrochemical properties of Polyacrylonitrile (PAN) electrospun separators in the presence of Polyvinylalcohol (PVA) hydrophilic materials and Malonic Acid (MA) crosslinker inside the lithium-ion batteries. The results showed that the M3 modified separator with the MA to PVA+MA (wt./wt.) optimum ratio of 37.5 % had the best performance in all tests. This separator had a value of 3.16 mS/cm in the ion conductivity test. Additionally, it had an electrolyte uptake of 1172 % (2.39 times more than the neat PAN separator) and thermal shrinkage of 7.4 % at 180 °C, where this value was 14.5 % for neat PAN separator at the same experimental condition. Furthermore, the acceptable performance in the battery performance tests was compared with other separators.
