Highlights

  • Cotton and PP fabrics coated with a chitosan matrix containing Cu2O@SDS NPs were developed.

  • The coating of the fabrics was carried out by using a dip-assisted layer-by-layer technology.

  • Low curing temperature and without expensive equipment or toxic chemicals were requirement.

  • The coating of fabrics developed provides a reduction in the infectivity of the SARS-CoV-2 virus.

Abstract

This paper describes the development of a coating for cotton and polypropylene (PP) fabrics based on a polymeric matrix embedded with cuprous oxide nanoparticles (Cu2O@SDS NPs) in order to inactivate SARS-CoV-2 and manufactured by a simple process using a dip-assisted layer-by-layer technology, at low curing temperature and without the need for expensive equipment, capable of achieving disinfection rates of up to 99%. The polymeric bilayer coating makes the surface of the fabrics hydrophilic, enabling the transportation of the virus-infected droplets to achieve the rapid inactivation of SARS-CoV-2 by contact with the Cu2O@SDS NPs incorporated in the coated fabrics.
