Papers by Keyword: Fluorinated Polyimides

Abstract: In this paper, we mainly investigated the properties of fluorinated polyimides film materials. Two aromatic dianhydrides, PMDA and ODPA were poly-condensed with four fluorinated diamines to prepare fluorinated polyimides by the two-step thermal imidization process. The properties of these polyimides were characterized by IR, TGA and UV-vis instrument. The organosolublility of these polyimides was tested in various organic solvents, such as NMP, DMF, DMAc. In addition, the effect of monomers’ molecular structure on the optical, soluble and thermal properties of these polyimides was also studied.
