What is 2-(4-Aminophenyl)-1H-benzimidazol-5-amine?

Description

2-(4-Aminophenyl)-1H-benzimidazol-5-amine (APBIA) is a synthetic raw material for the preparation of sulfonated polyimides containing benzimidazole (SPIBIs). The synthesised SPIBIs with polyhedral oligomeric silsesquioxane glycidyl ethers (G-POSS) can be used to prepare a number of novel organic-inorganic hybrid proton exchange membranes (PEMs). The obtained membranes exhibited good crosslink density at all gel fractions above 75%. The mechanical properties, oxidative stability and hydrolytic stability of the crosslinked membranes were significantly improved compared with those of pure SPIBI membranes.

The Uses of 2-(4-Aminophenyl)-1H-benzimidazol-5-amine

2-(4-Aminophenyl)-1H-benzimidazol-5-amine is a useful as an aerogel lithium battery separator.
