This study provides a comprehensive evaluation of film substrates following the rolling process. The investigation focuses on two substrate materials, polyimide film, and thermoplastic polyurethane. Through the manipulation of rolling cycle counts, we conducted a series of scratch tests, followed by a comprehensive analysis of how rolling impacts scratch formation.
