Researchers develop graphene oxide spray coating for antiviral protection of face masks
Researchers at Spain's IMDEA Materials Institute, Rey Juan Carlos University and Valladolid University have developed a new spray coating to improve the antiviral efficacy of personal protective equipment, notably face masks.
The team's system is based on nanoplatelets of graphene oxide (GO) spray coated via a simple one-step procedure over a poly(lactic acid) textile fabric, allowing a homogeneous coating. The incorporation of GO does not affect the textile structure nor its air permeability, while it increases its water contact angle, potentially preventing droplet trespassing.
