In this paper, a new type of electrostatic material, poly(vinylidenefluoride-co-trifluoroethylene) [P(VDF-TrFE], was introduced for the application of air filtration. It has native molecular dipoles that could create a strong electrostatic charges, and it could potentially enhance the filtration efficiency in the range of PM2.5 particles. To study its air filtration performance, we used electrospinning technology to create fiber mesh to serve as the filtering media. This technology has been successfully developed since 1934 with large specific surface area and extremely thin fiber diameter comparable with commercial filter media [1]. The objectives of using electrospinning nanofiber are lower energy consumption, higher filtration efficiency, and higher filter quality [2]. However, with decreasing fiber diameter, the pressure drop can prominently be increased, which means it also increases the energy consumption of filtration since the pressure drop is inversely proportional to the square of fiber diameter as shown in....

...In this work, we applied non-woven media to be a base media for electrospinning manufacturing and also to eliminate the problem of a higher pressure-drop under the relationship between packing density and filter quality. The superior of this design is...
