“…The background potential was 3.7 kV. In previous studies, pulsed or AC potential has been used in electrospray, basically to stabilise the jet or to control the jet break up process (Sample & Bollini, 1972;Balachandran, Machowski, & Ahmad, 1994). For example, Gonzalez et al (1999) added an AC field to the DC with appropriate strength and frequency to stabilise the jet obtained from high conducting liquids.…”

“…It has been reported that electrospray allows the production of fine solid particles of small standard deviation from about 100 µm down to a nanometer-scale without significant change in chemical composition and physical properties of the material to be sprayed. Balachandran et al [7]. used electrospray method to produce zirconia particles within the range of 50-500 μm by adjusting the applied ac frequency.…”

− Various solid structures were prepared by electrospray technique. In this process, liquid flows out from a capillary nozzle under a high electrical potential and is subjected to an electric field, which causes elongation of the meniscus to form a jet. In our study, by controlling the amount of polyvinyl pyrrolydone in precursor solution, the jet either disrupted into droplets for the formation of spherical particles or was stretched in the electric field for the formation of fibers. During the electrospray process, the ethanol solvent was evaporated and induced the solidification of precursors, forming solid particles. The evaporation of ethanol solvent also enhanced the mass transport of solutes from the inner core to the solid shell, which facilitated fabrication of porous and hollow structure. The network structures were also prepared by heating the collector.

“…As a driving force to generate a drop or a bubble in aforementioned EHD system, an external electric field has been used [5,[9][10][11][12][13][14][15]. Examination of previous studies elucidates that the dynamics governing drop formation depends highly not only on the electric field strength, but also on the type of electric field such as DC or AC electric field.…”
