Abstract

This invention relates in general to capacitors including one or more layers of dielectric material wherein at least one of the layers including a multiaxially oriented lyotropic liquid crystalline polymer (LCP) film. The present invention also provides lyotropic LCPs films having less than 0.5% residual ionic contaminants and a method of preparing such films and capacitors including such films. In preferred embodiments, the invention further provides a capacitor wherein the liquid crystalline polymer film has less than 0.5% residual ionic contaminants.
