Antimicrobial material

Technology description

The name of the technology: Antimicrobial material
Challenge: Hygiene products such as mouth masks and respirators are often a reservoir of viruses and harmful microbes. It is therefore advisable to use materials for these products that viruses and microbes themselves destroy. It is also an advantage to have such a material enriched, for example, air filters, when it is a preventive measure that ensures the penetration of harmful substances through these filters.
Description: The solution is a substrate with an antimicrobial surface layer, designed especially for respiratory masks and air filters. This antimicrobial coating contains two electrically conductive materials that are in electrical contact with each other. The essence lies in the fact that the substrate is made of breathable material. The essence lies in the fact that the substrate is made of breathable material. This breathable material is permeable to water molecules. The substrate or antimicrobial surface layer is further provided with an electrolytic substance from the group salt, hydroxide, acid and/or a combination thereof. The first electrically conductive material in the presence of a second electrically conductive material and electrolyte, which can also be water or air moisture, is subject to galvanic corrosion, and therefore there is a release of ions of this material that have an antimicrobial effect. The acceleration of the release of substances with antimicrobial properties is due to the presence of salt, hydroxide, acid and/or a combination thereof, which, by dissolving in water or air moisture, significantly increase its electrolytic properties. Thanks to this, the amount of viruses or bacteria on the surface of air filters and respiratory face masks will be reduced, thereby achieving a number of microbes below the minimum infectious dose.
Commercial opportunity: Substrate with antimicrobial surface layer, especially for respiratory masks and air filters, can be used mainly as part of the layer of respiratory face masks or as a surface treatment of air filters to eliminate a larger number of viruses and bacteria and minimize the retention time of viruses and bacteria on the surface of the respiratory face mask or air filter. The substrate can also be used for medical textiles such as dressings and/or patches or for covering body implants.
IP protection status: CZ Patent a Utility model in application phase. Nr. of Patent application 2022-359, nr. of Utility model application 2022-40181.
Development status:

Phase 3

Corresponds with TRL 5 and TRL 6

Technology validation and implementing it in real environment. Testing the technology outside of the laboratory and its adjustment to external conditions.

  • TRL 5 represents a state where the results of the real environment tests are known and there is an idea of how to deal with the problems found (if any)
  • TRL 6 is a state where a fully functional prototype already exists and is capable of fulfilling all its functions
