Abstract
Polymer solution interacts with the electric field in an electrohydrodynamic (EHD) spraying process. Charged polymeric solution forces polymer liquids to move, break into spray of fine droplets. EHD spraying has the ability to generate very small & uniform droplets of polymeric solution. It is envisaged that EHD Spraying is a promising technology to coat a polymer on substrate at submicron range. The polymer aggregation is important while coating. The process parameters including applied voltage, nozzle-collector distance, solution flow rate, and solution concentration plays an important role in polymer droplets aggregation on surface. Field strength is also plays important role while EHD spraying. Field strength is the rate of change of potential with respect to distance. This research paper investigates the effect of field strength on aggregation of polymer droplets.
