Patent number: 8248755Abstract: A polyimide resin is provided. The polyimide resin comprises the reaction product of a polyimide resin and an amine comprising a C1-10 hydrocarbon substituted with CN, F, SO2, SO, S, SO3, SO3?, PO, PO2H, PO3H, PO2?, PO3?2, CO, CO2?, CO2H, CONH, CONH2, NHCOHN, OCONH, OCO2, N, NH, NH2, NO2, CSNH, CSNH2, NHCSNH, OTi(OR4)3, or OSi(OR4)3 or combinations of these, wherein R4 is a C1-10 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.Type: GrantFiled: April 30, 2010Date of Patent: August 21, 2012Assignee: General Electric CompanyInventors: Gary William Yeager, Norberto Silvi, Patricia Chapman Irwin, Robert Colin McTigue
