When a charge neutral drop impacts on flat solid substrate, small air bubble is always trapped underneath due to the lubrication pressure coming from viscous stress in squeezed film. Herein we find experimentally and numerically that process of entrapment initial contact state with substrate can be profoundly altered via an external electric field. In field, induced stresses at bottom increase drastically right before contacts which acts against pressure, resulting reduced radius size. field...
Complex electrohydrodynamic behavior occurs during drop impact onto a solid surface under an external electric field. The process can be divided into three stages: (1) deformation of the in field prior to contact; (2) initial contact with substrate; and (3) rich postcontact phenomena. Herein we provide complete physical picture entire impacting various deposition modes are summarized phase diagram which sheds light on identifying appropriate fields for high-quality depositions without air...
