Influence of the operating parameters of the needle-plate electrostatic precipitator on the size distribution of aerosol particles

This work is devoted to the sintering of silver nanoparticle arrays in the form of lines by the local treatment with laser radiation with wavelengths of 527, 1054 and 1064 nm in pulsed and continuous laser modes. The silver nanoparticle lines were formed by the dry aerosol printing, free from organic solvents and surfactants. To form the lines with a width of 25–300 μm and a thickness of 0.1–15 μm a focused stream of nanoparticles with an average size of about 60 nm was used. It is shown that when using continuous laser radiation with a wavelength of 1064 nm, the minimal specific resistance of silver nanoparticle lines was achieved 3 times higher than that for the bulk material was reached.

In this paper, we demonstrate an ability to produce aerosol metal Al nanoparticles with plasmon resonance in the ultraviolet region in a spark discharge generator in pure argon atmosphere. The sizes of the obtained primary particles with metal Al core and natural oxide shell in the range from 4 to 50 nm, which were collected in agglomerates with mean size from 190 to 260 nm, were observed. Simulation extinction spectra according to Mi theory for obtained particle ensembles were calculated. It was experimentally and theoretically found that obtained nanoparticles ensembles demonstrate the broad extinction peaks with maximum below 250 nm depending on the synthesis conditions.

The influence of the morphology of oxidized copper nanoparticles on the deposition efficiency, packing density, and resistivity of microstructures obtained by dry aerosol printing was studied. It has been established that the thermal treatment of aerosol nanoparticles allows to vary their morphology from branched submicron agglomerates to compact spherical nanoparticles with a size of 20-50 nm. It is shown that the use of spherical nanoparticles in comparison with agglomerates allows one to obtain densely packed nanoparticles on substrate. Moreover, obtaining of semiconductor microstructures from oxidized copper nanoparticles on a plastic substrate with a resistivity of 0.01 Ohm • m was demonstrated.
