Quasicrystalline Lubricants for Aerospace Applications

Not Available The next generation of military energy storage capacitors will necessitate improvements in materials efficiency, energy density, and temperature reliability over existing devices. Similar performance issues are driving the consumer electronics market towards the development of high capacitance, low voltage, and small volume energy storage devices. These two market needs can be met by a single product which addresses the mutual concerns for high temperature stability and improved dielectric performance. TPL proposed to develop a high density material having a three-fold increase in energy storage density with improved thermal stability. A composite system is proposed consisting of two novel materials developed at TPL, polyimide copolymers with increased energy density and mechanical strength, and surface functionalized, nano-sized X7R barium titanate. Capacitor grade film of the composite materials will be fabricated and evaluated with regard to critical electrical performance parameters. TPL has extensive experience in dielectric polymers and hydrothermal titanate ceramics, including the development of doping methods to produce 50 nm size ceramic powders with flattened frequency and temperature response. Expertise in these two areas, in conjunction with industrial partners, will be used to develop dual-use materials to satisfy the mutual needs of military and consumer products.
