Research Institution
NanoSonic would produce highly ordered dielectric-polymer hybrid nanocomposites with high dielectric strength via the modification of high performance polymer backbones (demonstrated for high kV/dt applications) with controlled mole fractions of ferroelectric complexing and crosslink sites. Such materials result in flexible thin film, nanocomposites with extremely homogenous dispersions nanostructured BST particles, specifically as high energy-density (>15 J/g) capacitors for directed energy OSD platforms. The ultra-lightweight nanocomposites are designed to offer high voltage breakdown strength, high thermal stability, high electrical resistance, low CTE, low loss and performance over a wide service temperature range (Tg = -120°C, degradation > 400°C). Polyorganosiloxanes are commonly used as dielectric insulators, and the addition of proprietary pendent sidechain chemical groups increases both the number of BST complexing sites and the high temperature thermal stability needed for high power electronics and microwaves. NanoSonic’s novel manufacturing method for flexible dielectric films will be combined with our Metal Rubber technology currently used to impart in-situ electrodes on nearly any surface. The Dielectric-Metal-Rubber capacitors can be strained to greater than 1000% without loss of electrical conductivity or electrode cracking/spalling. Nanocomposite structure/property relationships for dielectric strength as a function of nanoparticulate content would be elucidated during this program to predict performance.
