Experiments on single event electrospraying

摘要

In order to use electrospraying as an on demand deposition method, well defined and reproducible single electrospraying events have been studied. To generate a single electrospraying event, rectangular voltage pulses superimposed on a constant bias voltage were applied, and optimum settings of the bias dc voltage for starting such an event were found. This onset point is related to a critical value of the effective surface tension before dripping starts.
