NASA's future space science missions cannot be realized without the state of the art high temperature insulation materials of which higher working temperature, high reliability, and low cost are highly desired. T/J Technologies proposes to develop a high temperature, durable, readily processable electrical insulation materials. The key element of our approach is the development and demonstration, in a breadboard configuration, the feasibility of a new high temperature polymeric composite material based on organic-inorganic nanocomposites with tailored structure and composition that will dramatically increase the Glass Transition Temperature and working temperature of the host polymer, polyimides. Future work of this proposed research, during phase II, will be mainly focused on developing all the associated technologies. The development of high working temperature, durable, radiation resistant electrical insulation materials is important for on-board propulsion and power systems for manned and unmanned deep space missions within NASA as well as electrical and microelectronic industries for applications such as capacitors, electric motors, circuit-printing films, semiconductor coating, etc.
