Mafilimu a polyimide

Filimu ya polyimide: filimu yapamwamba yopangidwa ndi polyimide, yomwe imapangidwa ndi condensation ndi kuponyera kwa phthalic anhydride (PMDA) ndi diaminodiphenyl ether (DDE) muzitsulo zamphamvu za polar, zotsatiridwa ndi imidization; Itha kugwiritsidwa ntchito ngati cholekanitsa cha mabatire a lithiamu, kutumikira kudzipatula maelekitirodi abwino ndi oyipa ndikuletsa mabwalo amfupi.
