Pre-charging polymer surfaces enhances droplet mobility and electrification
Shuaijia Chen, Kenta Morita, Dumindu Dassanayaka +4
Surface-bound electric charge on polymer materials can strongly influence droplet behaviour and solid-liquid charge transfer, but the mechanisms and the means to control these effe…
Polyelectrolyte adsorption at the solid-liquid interface favors receding contact line instability
Léa Delance, Diego Díaz, Arivazhagan G. Balasubramanian +3
Controlling the motion of non-Newtonian drops on surfaces is crucial for applications ranging from inkjet printing to biomedical devices and food processing. While the macroscopic…
Mechanisms in Slide Electrification of Liquid and Frozen Drops on Hydrophobic Surfaces
Rutvik Lathia, Benjamin Leibauer, Aaron D. Ratschow +2
The microscopic and fundamental origin of slide electrification, where droplets of water move across insulating surfaces accumulating and depositing electrical charges, is still de…
Surfactants Screen Slide Electrification
Xiaomei Li, Zhongyuan Ni, Xiaoteng Zhou +4
Water drops spontaneously accumulate charges when they move on hydrophobic dielectric surfaces by slide electrification. On the one hand, slide electrification generates electricit…
Chemical Physics of Controlled Wettability and Super Surfaces
Carolina Brito, Hans-Jürgen Butt, Alberto Giacomello
Wetting phenomena are widespread in both natural and technological contexts. Despite the well-established nature of this scientific field and our extensive knowledge of its underly…
How charges separate when surfaces are dewetted
Aaron D. Ratschow, Lisa S. Bauer, Pravash Bista +3
Charge separation at moving three-phase contact lines is observed in nature as well as technological processes. Despite the growing number of experimental investigations in recent…
Surface charge deposition by moving drops reduces contact angles
Xiaomei Li, Aaron D. Ratschow, Steffen Hardt +1
Slide electrification - the spontaneous charge separation by sliding water drops - can lead to an electrostatic potential of 1 kV and change drop motion substantially. To find out,…
Charging of dielectric surfaces in contact with aqueous electrolyte -- the influence of CO
Peter Vogel, Nadir Möller, Muhammad Nawaz Qaisrani +6
The charge state of dielectric surfaces in aqueous environments is of fundamental and technological importance. Here, we study the influence of dissolved molecular CO on the ch…
Enhancing condensation on soft substrates through bulk lubricant infusion
Chander Shekhar Sharma, Athanasios Milionis, Abhinav Naga +9
Soft substrates such as polydimethylsiloxane (PDMS) enhance droplet nucleation during the condensation of water vapour, because their deformability inherently reduces the energetic…
Printing surface charge as a new paradigm to program droplet transport
Qiangqiang Sun, Dehui Wang, Jiahui Zhang +8
Directed, long-range and self-propelled transport of droplets on solid surfaces, especially on water repellent surfaces, is crucial for many applications from water harvesting to b…
