Study of a polyaniline/polypropylene collecting electrode and its particle removal efficiency

Abstract

In this study, we successfully prepared conductive polyaniline (PANI) on a polypropylene (PP) plate to produce novel collecting electrodes for the removal of fine particles. The PANI/PP plates were assembled on an arrayed collector to produce high particle removal efficiency in an electrostatic precipitator. The PANI/PP plate was characterized using FT-IR spectroscopy, XRD, TG, SEM and EDS. The particle removal efficiency of the collecting plates can reach 90% for PM2.5. Furthermore, the effects of wind velocity, the space between the collecting plates and the surface resistance of the collecting electrodes, and the number of washing cycles on the particle removal efficiency were discussed.
