Accelerated Co-Designs of High-k Polymer Dielectrics
Abstract
Dielectric films with high capacitive energy storage density are essential elements for the fulfilment of the Navy~s future needs of pulsed power, power conditioning and energy storage. In a broader view, fundamental research in dielectric materials has been identified as a critical enabler for the payload efficiency and affordable high power density of integrated electric propulsion systems. Scalable dielectric material and film technologies with significantly increased storage capacity at the device level while maintaining the high cycle efficiencies and low loss of state-of-the-art capacitors are in great need. Through intensive researches sponsored by ONR, a polymer dielectric co-design platform has been developed and led to over a thousand polymers studied computationally, and several dozen polymers studied experimentally. The most promising polymers were those with a combination of large dielectric constant, low loss, moderate band gap, and high energy storage capacity, which included both organic and organometallic polymers. The objective of this program is to accelerate the co-designs of advanced polymer dielectrics by combining a targeted search over the expanded chemical and property spaces with high field characterizations to obtain scalable polymers with dielectric constants in excess of 10, low loss of less than 1%, and breakdown strength in excess of 600
