Abstract :
Four different approaches to develop materials for high-energy-density and high-voltage capacitors are presented: diamond like carbon films, chemically vapor deposited diamonds films, ULTEM polyetherimide films, and computer-modeled modified polyetherimide films. Following a brief discussion of the state-of-the-art, the status of the work on these materials is presented, which includes measurements of resistivity, dielectric constant and loss, and breakdown strength. The results are very encouraging and suggest that energy densities of 4-15 J/cm3 are possible
