  Background and aims: Nano-fibrous mats are one of the unique nonwoven materials that have been recently carried out in nanofiltration industry. The aim of this study was to synthesize nano-fibrous path mats using electrospining method following by determination of their efficiency for nanoaerosols removal.
Methods: The efficiency and pressure drop of nano-fibrous mats was measured using nano-scale sucrose aerosols with the particle size range of 70 -700 nm at different flow rates of 1.58 - 5 m.s -1. Cylindrical test system in a form of stainless steel with a filtration surface of 130 cm2 was built. Desired particles were generated using Electro spray 3480 model particle generator. Condensation particle counter PMS Models Micro LPS DAS of Boulder Company was used to measure the particle number concentration both before and after the filtration and then to determine the performance.
Results : Obtained results showed that the fibers diameter and pore size of synthesized nanofibers provide uniformity with the fiber diameter ranging from 20 to 70 nm. Our results revealed that the maximum permeability of nano-fibrous pads was related to 100 nm particles that were selected as MPPS in this medium. Considering the test particles size distribution it was found that with increasing the velocity the permeability and the pressure drops were increased and the quality factor was decreased.
Conclusions : this study shows that electrospinning is a promising technology for the synthesis of high performance nanoparticle filters.
