Description
A two-dimensional array of spots of deposited nanoparticles as small as 7 × 7 m was fabricated on a polymer film using a modified commercial nanometer aerosol sampler (NAS; TSI-model 3089) coupled with a surface-discharge microplasma aerosol charger (SMAC). The charged aerosol particles were electrostatically focused by a metal mesh (electrically grounded) on the polymer film (insulator) and electrode (3 kV). The effect of mesh geometry on the concentration ratio (focusing ratio × collection efficiency) was evaluated using monodisperse polystyrene latex particles with diameters of 48, 100, and 300 nm. The electrostatic focusing effect was also analyzed by a numerical simulation of the electrostatic field. The two-dimensional patterning of nanoparticles is an effective method in concentrating particles for the subsequent observation and chemical analysis of aerosol particles. In our experiments, the SMAC-NAS system achieved a net concentration ratio of more than 20 times for 48-and 100-nm particles, which would significantly shorten the aerosol-sampling time. The particle deposition patterns formed on a transparent polymer film may provide samples for analyzing the transmittance, luminescence, and other optical characteristics of deposited nanoparticles. © 2015 American Association for Aerosol Research.
