Abstract

The development of nanoscience and nanotechnology in recent years has promoted a great advance in the study of functional materials that have different physical and chemical properties, enabling their applications in innovative products for use in areas such as health, agronomy and others. Among the nanomaterials, polymeric nanofibers stand out, which are systems with high surface area and porosity, which can be used in the manufacture of new personal protective equipment, such as a filtering system applied to retain microparticles, bacteria or even viruses. These materials can be manufactured using biodegradable material associated with various low-cost microbicidal materials, presenting high potential for application in the health area. In this context, this project aims at the development of filtering nanomaterials using silver nanoparticles deposited on polymeric nanofibers produced by the technique of spinning by blowing in solution for deposition on a layer of textile fabric of a surgical mask. The second stage of this project consists of thermal, mechanical and mainly investigations of the filtering capacity of the system, and with potential application in surgical masks. (AU)
