Chemistry & industry
Applications
Description4,4'-(Hexafluoroisopropylidene)diphthalic anhydride (6FDA) is an aromatic organofluorine compound that is utilized as a dianhydride monomer. It is among the most frequently used dianhydride monomers due to its exceptional balance of mechanical and electrical properties. It is particularly prominent in the construction of colorless and transparent polyimides.
Uses4,4'-(Hexafluoroisopropylidene) diphthalic anhydride is involved in the synthesis of polyamides derived from terphenylenes, which is used for gas separation.
General Description4,4'-(Hexafluoroisopropylidene)diphthalic anhydride (6FDA) consists of two phthalic anhydrides bridged with a perfluoroisopropyl group and is mainly used in the synthesis of polyimides. Polyimides from 6FDA are commonly used in hybrid matrix membranes. The polyimide matrix provides good dispersion of the filler and can be loaded with up to 50 wt% filler. These membranes have been used for highly selective gas separation (CO2/CH4) and solar cell encapsulation (power conversion efficiency of silicon-based solar cells increased from 14.67% to 15.64%).
