Although the nanotechnology industry is an important factor to produce higher performance materials, the human exposition to nanoparticles continue increasing and becoming a serious threat to public health. Nanoparticles can cause many health problems including Alzheimer’s disease when inhaled. The fibrous filters are among the various equipment potentially able to remove particles efficiently from the air. There are many researches using electrospinning process to produce nanofibers, however applying these nanofibers in filtration area is still a challenge. The aim of this study is to produce PAN (polyacrylonitrile) electrospun fibers deposited on glass fiber substrate to be used as air filters. In order to determine the optimum manufacturing conditions, the effects of several electrospinning process parameters were analyzed as the solution concentration, collector to needle distance, flux rate, voltage and duration.

This study provides a promising air filter. It allows...
