Radius-controlled Rolled Structure based on the Graphene Oxide/Polypyrrole Composites with Polyvinyl Acetate Thin Film

The increasing popularity of flexible displays and wearable devices has promoted the development of flexible thin film substrates. These substrates offer many advantages over their rigid counterparts, including flexibility, light weight, and conformability. This study presents a novel approach to preparing a rolled polymer-based structure by rolling a thin film of polyvinyl acetate (PVA) to a specific radius. To enhance the electrical conductivity of the substrate, a layer of graphene oxide (GO)/ polypyrrole (PPY) composites were dropped cast onto the surface. The resistance of several rolled structures, each with a different weight ratio of GO/ PPY composites, was examined and compared. Overall, these findings provide important insights into the development of flexible thin film substrates for use in various applications.
