Investigating the properties of sulfone-containing transparent polyimide films through the combination of experimental and computational approaches In this study, two diamine monomers, 4,4′-(propane-2,2-diyl)bis(2-aminophenol) (PPAP) and 4,4′-sulfonyl bis(2-aminophenol) (SFAP), were copolymerized with three dianhydrides, 4,4′-(hexafluoroisopropylidene)phthalic anhydride (6FDA), cyclobutanetetracarboxylic dianhydride (CBDA), and 1,2,4,5-cyclohexanetetracarboxylic dianhydride (HPMDA), to...
