Recubrimiento Antiviral, Mascarilla con Filtro, CVDResumen
La Organización Mundial de la Salud recomienda el uso de mascarillas quirúrgicas para la protección personal contra la transmisión de enfermedades. Sin embargo, la mayoría de las mascarillas quirúrgicas disponibles en el mercado son desechables y no se pueden autoesterilizar para su reutilización. Por lo tanto, ante la crisis mundial de salud pública, la grave contaminación causada por las mascarillas desechables es inevitable. En este artículo, se presenta una novedosa mascarilla con filtro de bajo coste y excelente transpirabilidad que sustituye los derivados del petróleo de los filtros por un filtro ecológicamente correcto con propiedades optimizadas de forma sostenible a escala preindustrial (rollo a rollo). Se pasó un rollo de papel común por una cámara de vacío y se depositó mediante CVD. Se midieron la hidrofobicidad y la permeabilidad mediante ángulo de contacto, SEM y AFM. Las gotas no penetran el filtro durante un mínimo de dos horas. Además, los filtros demostraron ser eficaces en pruebas antimicrobianas y de transpirabilidad.
