Resumo(s):	New alternatives to the conventional wound dressings are being engineered. Here, we propose the processing of two biodegradable polymers, poly(vinyl alcohol) (PVA) and cellulose acetate (CA), in the form of films via a new method that combines principles of solvent casting and phase-inversion. Highly flexible and mechanically resistant films were obtained. PVA/CA films were then treated with the antibiotic vancomycin via two methods, blending and physisorption (via dopamine). Immobilization of vancomycin was proven efficient in promoting the films' antibacterial action against Staphylococcus epidermidis bacteria. Data demonstrates the potentialities of PVA/CA films for prospective wound healing applications.
