Coalescence Dynamics of PEDOT:PSS Droplets Impacting at Offset on Substrates for Inkjet Printing

Abstract

PSS is found similar to the charged droplets, which show that the charged nature of the polymer does not affect the coalescence behavior. Furthermore, different spreading regimes are identified and the governing forces in each regime are described using a semianalytical formulation derived for the coalescence of two droplets. The model has been found to accurately provide insight into the various mechanisms that play a role during the complex spreading event.
