Abstract

The development of nanoscience and nanotechnology in the last years promoted an expressive advance on the functional materials study that show differentiated physical chemical properties, allowing their applications in innovate devices for using in different areas, as such: medicine, health, agronomy, etc. Among the nanomaterials, the polymeric nanofibers are in evidence, are systems with high superficial area and porosity, and can use in the manufacturing of new personal protective equipment, as such a filter applied system in the retention of microparticles, bacteria or virus. These materials can be manufactures using biodegradable materials with different microbicidal materials and low cost, and with potential application in the area of public health. This Project aims to the development of filter biodegradable nanomaterials using graphene oxide and silver nanoparticles on polymeric nanofibers manufactured by electrospinning technique for deposition in polymeric on tissue layer of surgical mask. The second step of this project are the thermal and mechanical investigations, principally of filter capacity system, and with potential for application in surgical masks. (AU)
