The development of advanced polymers is a cornerstone of modern material science, driving innovation across numerous industries. Within this domain, sulfonated polyimides (SPIBIs) are recognized for their exceptional thermal stability, mechanical strength, and ion conductivity, making them ideal for applications such as proton exchange membranes (PEMs) in fuel cells and separators in high-performance batteries. Central to the synthesis of these advanced SPIBIs is the chemical intermediate 2-(4-Aminophenyl)-1H-Benzimidazol-5-Amine, identified by CAS 7621-86-5.

As a key raw material, 2-(4-Aminophenyl)-1H-Benzimidazol-5-Amine, when incorporated into polyimide structures, imparts unique properties. The presence of the benzimidazole moiety and the amino groups facilitates the subsequent sulfonation process, leading to polymers with improved hydrophilic character and proton transport capabilities. Furthermore, the incorporation of materials like polyhedral oligomeric silsesquioxane glycidyl ethers (G-POSS) alongside SPIBIs derived from this intermediate results in novel organic-inorganic hybrid proton exchange membranes that exhibit superior crosslink density and enhanced stability compared to their pure SPIBI counterparts.
