Abstract

Abstract: The European dependencies for raw materials supply from foreign countries have been unquestionably shown by COVID‐19 outbreak and have become particular evident from the slow response to the need for high quality personal protective equipment (PPEs). Among all medical devices, surgical face masks have earned themselves a primary role for the containment of the epidemic. In this context, our work aims at improving the barrier effect of surgical mask by depositing on their external surface a mixture of bioactive compounds, mainly polyphenols, extracted from agronomical sources. The main objective is the integration of the biorefining of agri‐food solid wastes with the potential virucidal properties of the polyphenolic extracts for the treatment of PPEs. Abstract : The experimental workflow proposed in this work. Vegetable wastes are selected, dried, crush into powder and extracted with 70 % ethanol. The solution is used to cover the surface of surgical face masks and improve their barrier effect against pathogens.
