Abstract
Many authors have observed in polymer-metal contact charging a linear relationship between charge density and metal work function. Obviously, measured density is apparent density because a polymer film surface is never a perfect plane. The true density is depending on the polymer surface microroughness and the applied pressure, both parameters having a large influence on the areas effectively in contact.The purpose of the present paper is to provide a contribution to the study of this phenomenon by combining classical contact charging measurement and assessment by various methods, optical or mechanical, of the polymer surface structure. A series of PET film samples having various microroughness has been used.It has been observed that, for a given pressure, a good correlation exists between charge density and surface microroughness.
