The Effects of Viscoelasticity in the Peeling of Polymeric Films

Abstract
A method to compute the interfacial fracture energy of a polymer film bonded to a rigid substrate, using the measured quantities of a peel test, is presented. The formulation is general and will accept any polymer which can be modeled as a linear viscoelastic material. The method is used to analyze the peeling of a polyimide film and a relationship between the fracture energy, the peel force, the speed of peeling and the thickness of the film is derived.
