Nebulization of Nanocolloidal Suspensions for the Growth of Nanocomposite Coatings in Dielectric Barrier Discharges

Abstract : The nebulization of colloidal suspensions is analyzed by dynamic light scattering, scanning, and transmission electron microscopies. While primary agglomeration can be important for many nanoparticle-solvent couples, our results indicate that for TiO2 nanoparticles dispersed in water, secondary agglomeration also occurs during nebulization. When nebulization is realized immediately after sustaining a plane-to-plane dielectric barrier discharge at atmospheric pressure, the collection efficiency of TiO2 nanoparticles increases due to the presence of a remanent electric field between the two electrodes. Finally, these findings are used to deposit SiO2-TiO2 nanocomposite thin films by alternating the deposition of dense silica-like layers in a Townsend discharge and the collection of TiO2 nanoparticles through nebulization of the nanocolloidal suspension.
