High comprehensive properties of colorless transparent polyimide films derived from fluorine-containing and ether-containing dianhydride.

ABSTRACT: Fluorinated colorless transparent polyimide (CPI) films are crucial for flexible displays and wearable devices, but their development is limited by high costs and relatively low mechanical properties. In this study, a series of colorless transparent polyimide films was synthesized by incorporating the cost-effective ether-containing diamine, 4,4'-isopropylidenediphenoxy bis(phthalic anhydride) (BPADA), into commercially available 4,4'-(hexafluoroisopropyl)diphthalic anhydride (6FDA) and 2,2'-bis(trifluoromethyl)benzidine (TFMB). The comprehensive properties of the films were systematically investigated using a combination of experimental and numerical methods, including molecular dynamics (MD) simulations and density functional theory (DFT). This study focuses on exploring the influence of
