A polyimide resin is provided. The polyimide resin comprises the reaction product of a polyimide resin and an amine comprising a C 1-10 hydrocarbon substituted with CN, F, SO 2 , SO, S, SO 3 , SO 3 − , PO, PO 2 H, PO 3 H, PO 2 − , PO 3 −2 , CO, CO 2 − , CO 2 H, CONH, CONH 2 , NHCOHN, OCONH, OCO 2 , N, NH, NH 2 , NO 2 , CSNH, CSNH 2 , NHCSNH, OTi(OR 4 ) 3 , or OSi(OR 4 ) 3 or combinations of these, wherein R 4 is a C 1-10 aliphatic or aromatic hydrocarbon. The resin may be used to provide a thin film that in turn, may advantageously be used to form, wholly or in part, articles such as capacitors, sensors, batteries, flexible printed circuit boards, keyboard membranes, motor/transformer insulations, cable wrappings, industrial tapes, interior coverage materials, and the like. In particular, a capacitor comprising the thin film and methods of making the same are also provided. |
