The effect of triboelectric behavior of polytetrafluoroethylene (PTFE) on the filtration performance of common air-purified filters was studied. Variations of triboelectric charge density on PTFE films were analyzed by four typical parameters (cycle, applied load, contact area and velocity). The results demonstrated that the addition of PTFE fibers could significantly improve the filtration property of air-purified materials, owning to the accumulation of triboelectric static charge on the fibers.
