Filtration Efficiency of Electret Air Filters Reinforced by Titanium Dioxide
In this study, titanium dioxide (TiO<sub>2</sub>), a mineral with a potential and supercapacitor, is used as the reinforcing material to improve the filtration efficacy of electret melt-blown fabrics. Next, the electret melt-blown fabrics are evaluated in terms of surface voltage and fil...

The test results indicate that the filtration efficiency is proportional to the ratio of TiO<sub>2</sub> and electric field intensity.
