Polymer films are widely used as substrates for flexible devices. For the development of mechanically durable and flexible devices, it is highly desired to analyze the fatigue behavior of polymer films under cyclic bending. However, there are few studies on the bending fatigue behavior of polymer films. In this study, we analyzed the bending fatigue behavior of oriented poly(ethylene terephthalate) films in terms of a radius of curvature and heat generation.
