Abstract

In this study, we carried out experiments to study penetration of airborne carbon nanotubes (CNTs) through a screen filter. An electrospray system was employed to aerosolize suspensions of multi-wall CNTs. The generated airborne CNTs were characterized by electron microscopy, and the length and diameter were measured. In the filtration experiments, the challenging CNTs are classified by a differential mobility analyzer. Monodisperse CNTs with the same electrical mobility were then employed to challenge the screen filter. Penetration was measured for CNTs in the range of 100-400 nm mobility diameters. The results showed that the CNT penetration was less than the penetration for a sphere with the same mobility diameter, which was mainly due to the larger interception length of the CNTs. We compared the modeling results using single-fiber filtration efficiency theories with the experimental data, and found that the effective interception length can be approximated by the CNT aerodynamic diameter multiplying a scaling factor. A hypothesis is proposed to understand the observation.
