The safety of personal protective equipment (PPE) is very important, and so is the choice of materials used. The ability of electrostatic charges (ESCs) generated from the friction of engineered materials to attract or repel viruses has a significant impact on their applications. This study examined the ESCs generated on the surface of PPE used by healthcare workers to enhance their potential effectiveness in protecting the wearer from viruses. This is a crucial consideration for the newly emerged severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), which has a negative charge. The magnitudes and signs of generated ESCs on the surfaces of the PPE were determined experimentally using an Ultra Stable Surface DC Voltmeter. The high negative ESCs acquired by the polyethylene disposable cap and facemask are expected to repel negatively charged viruses and prevent them from adhering to the outer layer of the material. Also, the choice of polypropylene for facemasks and gowns is excellent because it is an aggressively negatively charged material in the triboelectric series. This property guarantees that facemasks and gowns can repel viruses from the wearer. However, the positive ESCs generated on latex glove surfaces are of great concern because they can attract negatively charged viruses and create a source of infection. In conclusion, it is necessary to ensure that PPE be made of materials whose surfaces develop a negative ESC to repel viruses, as well as to select polyethylene gloves.
