Charging of Nanoparticle Aerosol

Abstract

A nanoparticle aerosol charging is one of the most important nanotechnologies because only Coulombic force working on charged particles in an external electric field can control motions of nanoparticles in gas phase. Recent studies on nanoparticle aerosol charging are reviewed. For bipolar charging, three chargers developed by Lee et al., Kwon et al. and Kimoto et al. are explained. For unipolar charging, five chargers developed by Chen and Pui, Hernandez-Sierra et al., Han et al., Kwon et al. and Kimoto et al. are described.
