The Materials Genome Initiative was established "to create a new era of policy, resources, and infrastructure that support U.S. institutions in the effort to discover, manufacture, and deploy advanced materials twice as fast, at a fraction of the cost".  Through the process of rational co-design, a series of new polymers, over 50, were prepared and tested for application as dielectrics for pulsed-power high energy dielectrics.  Emphasis on the rational co-design will be given from the wet-chemist perspective, and how this process is an extremely powerful tool for rapidly generating new polymers for a given application.  From this work, polymer free-standing films having dielectric constants in excess of 5 were made, with the highest being slightly above 8.  All of these polymers exhibit loss tangents of less than 0.03, with many of them below 0.01.  Interestingly, high-throughput density functional theory guided the wet-chemist's research in the direction of metal containing polymers and the prepared and characterized homopolymers included metals such as Tin, Zinc, Cadmium, and Titanium in the main chain.  Many of these polymers, such as the class of flexible aliphatic polyimides, exhibit loss tangents below 0.03 up to 150 degrees celsius.  Dielectric polymers such as these could find application in capacitors for catapulting, and electric vehicles.
