Abstract
Electrospinning is simple versatile technique to produce polymeric nanofibers by means of electrostatic force. Electrospun fibers typically have a diameter of several tens of nanometers to several micrometers. Recently, there has been a promising interest in utilizing polymeric nanofibers as dust collection devices capable of filtering fine dust particles from the atmospheric aerosol. Notably, the fine fibrous structure can help to achieve a high filtration efficiency with low pressure drop.

In this study, we aimed to develop a light-transmitting filtration device that can be directly applied to windows by employing electrospinning on a metal mesh substrate. We evaluated the performance of the electrospun nanofibrous filters in terms of filtration efficiency and light transmittance. The experimental results show that the electrospun nanofiber filters have a high filtration efficiency of over 90% while maintaining light transmittance of 70%. Furthermore, we have demonstrated the feasibility of adding functional materials into the polymer solution directly, allowing for the application of diverse functionalities to the filter material.
