Kilogram Scale-up of Dielectric Polymers for High Temperature, High Energy Density Capacitor Applica
Abstract
Approved for Public Release: The proposed project involves the scale-up of several new polymers that were conceived and prepared th,rough an Office of Naval Research Multi-Disciplinary University Research (MURI) Initiative. Specifically, three dielectric polymers, were chosen based on their ease of synthesis and ability to scale, their cost-of-goods, and their superior dielectric properties.,Each dielectric polymer will be scaled from an original 10 (x2) to 100g (x1) synthesis to 2 kilograms. In going by scales of 10, in, which syntheses typically can be scaled by 10x the quantity without sacrifice to yield using the same reaction conditions, one of t,he polymers to be scaled, defective polyetherimide will first be scaled to 2 kg, after all the parts for a 10 or 20 kg reactor are r,eceived. The other two polymers, both prepared by Ring Opening Metathesis Polymerization, will be scaled to 100g before scaling to,2 kg to ensure success of pilot-scale synthesis. All polymers produced at the small pilot scale will be characterized by nuclear ma,gnetic spectroscopy as well as thermal analysis and results will be compared to data acquired on the polymers at smaller scale. Eac,h of the three 2 kg dielectric polymers will be shipped to Purdue University where they will be solution processed roll-to-roll (R2R,) to produce dielectric films that will be sent back to University of Connecticut for dielectric testing. Breakdown of these polyme,rs as well as other dielectric data will be compared to data for the same polymers reported during the MURI program. Further, we an,ticipate that these polymers will be advertised and shipped to interested industries for high stress testing to evaluate their poten,tial performance for industry-intended Navy application.
