Graphene masks with ‘non-woven’ textiles more effective than normal

Researchers from the Center for Physics of Condensed Matter (IFIMAC) of the Autonomous University of Madrid (UAM) are developing new technologies to manufacture protective masks based on ‘non-woven’ textiles modified with graphene.

Investigators try develop safer tissues to avoid contagion by infectious pathogens and more specifically, by viral particles. With them they could make more effective masksAnd for this purpose, this versatile material comes into play with as much future projection as graphene, with which you can create from smart garments to asphalt for roads, batteries for electric cars, wearable technology, leading footwear and a very long etcetera.

The team of the Center for Physics of Condensed Matter (IFIMAC) of the Autonomous University of Madrid (UAM) is looking for coining an innovative fabric manufacturing technology based on modifying ‘non-woven’ textiles (not woven, in English). These are formed from fibers joined by mechanical, thermal or chemical procedures, but not spun, such as chamois.

The material used in most of the filters of the current masks is non-woven polypropylene. In the near future textiles could be modified with graphene and derived materials.

Three Spanish companies are part of the project: Nanoinnova Technologies, which supplies graphene and derivatives; Iberian non-woven, which produces nonwoven woven materials, and Elastic Textile, dedicated to the manufacture of elastic orthopedic products, who is the one who will produce the masks, as reported by the Sinc Agency.

“We intend to incorporate two-dimensional materials such as graphene and / or derivatives thereof, for example graphene oxide, and thus generate a specialized antiviral barrier in SARS-CoV-2”, the researchers say. They claim that the process is simple and scalable, based on a developed patent that allows the generation of graphene ‘inks’.

The purpose of the project is to develop a technology that helps improve the effectiveness and comfort of masks and other prophylactic textiles designed against the SARS-CoV-2 virus, but adaptable to other pathogens.
