Imbibition is capillary-driven transport where liquid invades a textured surface favorable to the spreading liquid41. We investigated the wetting behavior of EGaIn on the metal-deposited, microstructured surface in HCl vapor (Fig. 1). Copper was chosen as the metal for the underlying surface. On flat copper surfaces, … See more To investigate the effect of the topographical dimensions of the patterns on the wetting and imbibition of EGaIn, we varied the dimensions of the Cu-coated posts. Figure 2 reports the contact angles and imbibition of … See more Owing to the liquid characteristics of EGaIn, the EGaIn-coated Cu/PDMS (EGaIn/Cu/PDMS) can be used for flexible and stretchable electrodes. Figure 5a compares the change in the resistance of the pristine … See more The imbibition of EGaIn on the post-patterned Cu/PDMS enables the EGaIn patterning via selective wetting (Fig. 4). When EGaIn droplets are placed on the post-patterned region and are exposed to HCl vapor, EGaIn … See more WebGallium based eutectic alloys are one of the promising substitutes for mercury.

WebGallium is a metal that literally melts in your hand. It has low toxicity, near-zero vapor pressure, and a viscosity similar to water. Despite possessing a surface tension larger than any other liquid (near room temperature), gallium can form nonspherical shapes due to the thin, solid native oxide skin that forms rapidly in oxygen. These properties enable new … WebA novel phenomenon of electrochemically enabled reactive wetting, coating and spreading of gallium-based liquid metals within porous copper (Cu) was observed, and its mechanism was demonstrated. Its extensive applications including in the fabrication of large-area conductive film patterns, transfer-printing technology and the preparation of ...
