Electret Filter Based on Vanadium-containing Polytetrafluoroethylene for Treatment of Gas Media to Remove Solid Particles

Hybrid electret materials with increased surface charge thermal stability based on polytetrafluoroethylene films treated with vanadium oxochloride vapor and water are synthesized. A model of an electret filter for air treatment to remove solid particles using a modified and initial polytetrafluoroethylene film is proposed and tested. Comparative tests of a polytetrafluoroethylene film with and without vanadium oxide structures on the surface as filter material are carried out. In the presence of vanadium oxide structures in the composition of polytetrafluoroethylene, the efficiency and dust capacity of an electret air filter based on it increase by more than 90%.

Automated summary

Hybrid electret materials with increased surface charge thermal stability were synthesized by treating polytetrafluoroethylene films with vanadium oxochloride vapor and water. A model of an electret filter using a modified polytetrafluoroethylene film for air treatment was proposed and tested. Comparative tests between polytetrafluoroethylene films with and without vanadium oxide structures on the surface as filter material were conducted, showing that the presence of vanadium oxide structures significantly increased the efficiency and dust capacity of the electret air filter by over 90%.
