Synthesis and structure of fluorinated polyimide (FPI) with pentafluorophenyl side group

Caption

A diamine with a side group of pentafluorophenyl, 5FBODA, was synthesized and copolymerized with HFBAPP and 6FESDA to form a fluorinated polyimide, effectively reducing the dielectric constant and dissipation factor, while improving the elongation at break.
