Scientists from Perm Polytechnic University have created a new filtering material made of coal and copper. It retains 98% of bacteria and can be used in masks and respirators, the university's press service reported.
Scientists at PNRPU have developed a filtering material based on coal fabric and copper, capable of providing 98% protection against bacteria. The product is intended for use in masks, respirators, or filter absorbers and will be useful for medical institutions, chemical laboratories, and industries with high requirements for air sterility.
Coal fabric with added copper particles was used as the raw material for creating the filtering material. To assess the effectiveness of the material, the authors conducted two experiments. In the first, they placed samples in a nutrient medium containing bacteria and analyzed the zones where microorganisms died. In the second experiment, they directed a stream of contaminated air through the filter.
Tests have shown that the filter reliably protects against microorganisms.
This confirms the possibility of using our product in personal respiratory protection equipment and as an air filter absorber for disinfecting the environment.
Earlier, Nizhny Novgorod scientists developed a material for bioprinting, allowing the creation of skin, bones, blood vessels, and other tissues.
