Pokraskin The corona discharge technique consists of having the polymer film pass over a metal electrode coated with a dielectric material which receives a high voltage from a high-frequency generator (10-20 kHz). Normally the voltage increases cyclically until the gas ionises, generating a plasma at atmospheric pressure that is known as ‘corona discharge’.
This is a highly effective treatment for polyolefins that creates adhesion-enhancing carbonyl groups on the surface and raises the surface energy of the polymer [3].
