Hybrid films of novel fluorinated polyimides and hyperbranched cyclotriphosphazene polymer for enhanced flame retardancy, thermomechanical properties, and reduced dielectric constant†

This study synthesizes novel polyimide (B2FO PI) films using 4,4'-(1,4-phenyleneisopropylidene) diphenoxy bis(2-(trifluoromethyl)-4-aminobenzene) (B2FDA) and 4,4'-oxydiphthalic anhydride (ODPA), as well as polyimide (PI) hybrid films incorporating a hyperbranched fluorinated cyclotriphosphazene polymer....
