2,2'-Bis(trifluoromethyl)benzidine is an important monomer for the synthesis of polyimides. Polyimide synthesized with 2,2'-bis(trifluoromethyl)benzidine as monomer introduces fluorine groups, fluorine elements have a small atomic radius and high electronegativity, so that polyimide retains excellent comprehensive properties while giving it many unique properties, such as thermal stability, chemical inertness, excellent mechanical properties, etc. 2,2'-Bis(trifluoromethyl)benzidine is mainly used in the fields of microelectronics and optoelectronics for the preparation of very low dielectric constant, very low surface free energy, extremely high mechanical strength, extremely high wear resistance, colorless and transparent PI materials.
