Electrohydrodynamic Manipulation of Sessile Droplets by the In-Plane Electric Fields Rafael Granda Neto (23291998) Electrohydrodynamics This doctoral thesis is devoted to the exploration and understanding of the physical principles of electrohydrodynamics to develop and facilitate innovative processes of painting and coating of large dielectric surface areas with less material and a higher rate; aiming at optimizing these processes and reducing final production costs. From the beginning, this comprehensive study explores the effects of the in-plane electric fields (with DC voltages in the kV-range applied) on sessile droplets of multiple pure liquids, solvents, colloidal suspensions (with particles and pigments) and conducting polymers commonly used in painting and coating processes. This fundamental research aims at understanding the principles and mechanisms of interaction of the in-plane electric fields and sessile droplets through in-depth experimental, theoretical and numerical studies. Furthermore, this electric field-assisted approach aiming at an increase in the painting and coating efficiency, leads to multiple experimental results and provides a deeper understanding of sessile droplet manipulation by the in-plane electric fields on solid and porous dielectric surfaces. The present work attempts to fill significant knowledge gaps in this field. 2025-12-01T00:00:00Z Text Thesis 10.25417/uic.31451614.v1 https://figshare.com/articles/thesis/Electrohydrodynamic_Manipulation_of_Sessile_Droplets_by_the_In-Plane_Electric_Fields/31451614 In Copyright Open Access after 2028-01-01
