Menetelmä viruspatogeenien läpipääsyn estämiseksi

摘要

The invention discloses a method of preventing transmission of viral pathogens between a source of viral pathogens and a target of said viral pathogens comprising positioning between said source and said target a microporous membrane material comprising: 1) a thermoplastic polymer or polytetrafluoroethylene and 2) a water- and oil-repellent fluorochemical compound which provides said membrane with oloephobic, hydrophobic and viral barrier properties, said membrane being oriented in at least one direction.
