The performance of personal protective equipment fabrics for COVID-19 health care practitioners was improved by polyvinyl alcohol (PVA) coating The PVA enhances fabric’s resistance to body fluid penetration, on the other hand, also increases its hydrophilic properties However, hydrophobic is required to prevent microdroplets and body fluid wetting on the fabrics The hydrophobic effect was increased by immersed the fabrics in silica nanoparticles that resulted in a water contact angle of 133 41° ± 10 8°
