Recent advances in non-perfluorinated sulfonic acid proton exchange membranes in the energy field

“…In this study, the mechanism of radiation cross-linking in enhancing the thermal stability of the membrane was elucidated, emphasizing the need to carefully control conditions to balance other membrane properties during the radiation process. Balasubramanian et al 70 synthesized a stilbene membrane containing a sulfonated polyimide membrane, doubling the hydrolytic stability and further enhancing the oxidation stability of the membrane material after photo-crosslinking. Sohn et al 71 synthesized ETFE-based proton exchange membranes through synchrotron radiation method, exhibiting high proton conductivity, lower water absorption and size change, and higher chemical stability compared to non-crosslinked membranes.…”

“…Sohn et al 71 synthesized ETFE-based proton exchange membranes through synchrotron radiation method, exhibiting high proton conductivity, lower water absorption and size change, and higher chemical stability compared to non-crosslinked membranes. The studies by Balasubramanian 70 and Sohn 71 highlighted the influential mechanisms of radiation cross-linking on membrane properties, such as oxidation resistance, proton conductivity, and water absorption. They also provided crucial insights and improvement strategies for incorporating radiation cross-linking into high-performance membrane materials, signifying its strong guiding significance.…”

Design of 3D printed metal frame nested porous polyimide composites

“…Porous polyimide (PPI) could store a small amount of oil in the pores and exhibits excellent friction and wear performances [1][2][3], which has attracted great attention in fields of polymers and tribology [4][5][6]. PPI is usually used as oil reservoir or bearing cage under oil shortage or oil restricted conditions, such as control force gyroscopes and flywheels [7][8][9][10][11].…”
