2,2'-Bis(trifluoromethyl)benzidine is an important monomer for the synthesis of polyimide, polyimide synthesized with TFMB as the monomer for the introduction of fluorine groups, fluorine has a very small atomic radius and a high electronegativity, so that the polyimide retains the excellent overall performance at the same time to give it many unique properties, such as thermal stability, chemical inertness, excellent mechanical properties, etc.
TFMB is mainly used in the field of microelectronics and optoelectronics for the preparation of PI materials with very low dielectric constant, very low surface free energy, very high mechanical strength, very high abrasion resistance, colorless and transparent, and it is the most well-known monomer among all fluorine-containing PI diamine monomers.
