Are Contact Angle Measurements Useful for Oxide-Coated Liquid Metals?

LANGMUIR, 37(37), 10914–10923.

By: I. Joshipura n, K. Persson n, J. Oh n, M. Kong n, M. Vong n, C. Ni n, M. Alsafatwi n, D. Parekh n, H. Zhao *, M. Dickey n 

TL;DR: This work establishes that static contact angles for gallium-based liquid metals have no utility despite the continued and common use of such angles in the literature and provides recommendations and best practices for wetting experiments, which may find use in applications that use these alloys such as soft electronics, composites, and microfluidics.

2020 journal article

Metallophobic Coatings to Enable Shape Reconfigurable Liquid Metal Inside 3D Printed Plastics

ACS APPLIED MATERIALS & INTERFACES, 13(11), 12709–12718.

By: J. Ma n, V. Bharambe n , K. Persson n, A. Bachmann n, I. Joshipura n, J. Kim *, K. Oh*, J. Patrick n, J. Adams n , M. Dickey n 

author keywords: liquid metal; additive manufacturing; reconfigurable circuit; metallophobic surface; liquid metal actuation; 4D printing
TL;DR: It is shown that silica particles suspended in an appropriate solvent can be injected inside cavities to coat the walls, and this technique creates a transparent, nanoscopically rough coating that prevents adhesion of liquid metals on various 3D printed plastics and commercial polymers.

Electrowetting without external voltage using paint-on electrodes

LAB ON A CHIP, 17(6), 1069–1075.

By: C. Eaker n, I. Joshipura n, L. Maxwell n, J. Heikenfeld * & M. Dickey n 

TL;DR: This work presents a new method to dramatically reduce the complexity of electrode and dielectric fabrication while enabling multiple performance advances and opens up new application spaces for electrowetting (e.g. stretchable substrates, soft and injectable electrodes) while achieving large changes in contact angle without the need for an external power supply.
