Abstract

The present work aims to develop the electrostatic charge (ESC) generated from the triboelectrified fibers of polypropylene (PP) layers of the medical facemask caused by the air of inhalation and exhalation to repel the negative charged viruses such as Covid-19 out of the facemask. The effect of separating PP layers by different materials on ESC is investigated. The tested materials are copper and iron coils wrapped on cartoon spacer of 0.5 mm thickness and inserted between the PP layers. PP and PE nets as well polytetrafluoroethylene (PTFE) strings were tested as separating materials. In addition to that, carbon fibers and copper textile were tested. Fibrous polyester (PET) strings of 2.0 and 3.0 mm diameter weaved in PP middle layer were inspected.
 
It was revealed that the surface area activated by ESC increased  in condition of the separation of PP layers. As result of that, the electric field induced inside the gap in front of the facemask increased, where the effect of the electric field induced by copper and iron wires was significant. Besides, presence of the wires and strings inserted between PP layers increased the gap between PP layers and therefore increased ESC. Inserting PP and PE nets between PP layers increased ESC due to the increase of area rubbed by air. Conductive materials such as copper textile and carbon fibers generated relatively lower ESC than that generated in the presence of polymeric spacers due to the leakage of ESC from the charged PP layers. Insulated copper wires showed higher ESC than uninsulated ones. Fibrous PET strings weaved in PP layers showed the highest values of ESC due to increase of their surface area.
