Spray Coating Oxidized Graphene-Based Materials Makes Polyurethane Surfaces Antibacterial and Biocompatible: A Promising Approach for Medical Devices.

ABSTRACT: Preventing bacterial infections remains a primary concern for healthcare systems and patients. Polyurethane (PU) is widely used in various invasive medical devices, improving PU surfaces─particularly by reducing bacterial adhesion─a highly sought-after goal. This study explores the spray coating of PU-based medical devices with oxidized graphene-based materials (GBMox) as antibacterial agents, specifically oxidized graphene nanoplatelets (GNPox) and graphene oxide (GO). Different formulations, with and without PU as a coating binder, were investigated to assess the potential for tuning the coating based on the intended application. The resulting coatings were characterized in terms of morphology using Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM), along with wettabil
