A summary of corona charging methods

Abstract

Corona charging is a powerful method for studying storage and electric charge transport in dielectric films. The development of this technique for the study of polymer foils is summarized. The improvement achieved with the use of a biased vibrating grid, allowing the measurement of the potential buildup is commented on. Results obtained keeping the charge current constant are discussed. Other developments aimed at getting more uniform charge deposition are also discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
