Abstract

Surface patterning of liquid metals (LMs) is a key processing step for LM‐based functional systems. Current patterning methods are substrate specific and largely suffer from undesired imperfections—restricting their widespread applications. Inspired by the universal catechol adhesion chemistry observed in nature, LM inks stabilized by the assembly of a naturally abundant polyphenol, tannic acid, has been developed. The intrinsic adhesive properties of tannic acid containing multiple catechol/gallol groups, allow the inks to be applied to a variety of substrates ranging from flexible to rigid, metallic to plastics and flat to curved, even using a ballpoint pen. This method can be further extended from hand‐written texts to complex conductive patterns using an automated setup. In addition, capacitive touch and hazardous heavy metal ion sensors have been patterned, leveraging from the synergistic combination of polyphenols and LMs. Overall, this strategy provides a unique platform to manipulate LMs from hand‐written pattern to complex designs onto the substrate of choice, that has remained challenging to achieve otherwise.

Abstract

Despite significant progress in the field of wearables and flexible electronics, there are hardly any reports describing the overall implementation of these systems, from the design of electrical interconnects and substrates to the choice of electronic components. Researchers working on materials for flexible electronics are sometimes disconnected from those designing the electronic circuits for such applications. Herein, an overview of the essential design requirements for flexible electronics is presented. It includes discussions regarding communication protocols, design and implementation of electrical interconnects, choice and fabrication of substrates, and choice of electronic components for flexible systems. The functionalities of these electronic components are comprehensively discussed with consideration of the energy budget, in terms of power consumption, also presented. Additionally, the components of power generation and storage are explored with respect to their market accessibility. The field of wearable electronics is highly interdisciplinary and such information is essential for eventual standardization of the field. [ABSTRACT FROM AUTHOR]

17. Polydopamine Shell as a Ga3+Reservoir for Triggering Gallium–Indium Phase Separation in Eutectic Gallium–Indium Nanoalloys

Arifur, Tang, Jianbo, Yang, Jiong, Mousavi, Maedehsadat, Mayyas, Mohannad, Cao, Zhenbang, Centurion, Franco, Christoe, Michael J., Zhang, Chengchen, Wang, Yifang, Merhebi, Salma, Baharfar, Mahroo, Ng, Gervase, Esrafilzadeh, Dorna, Boyer, Cyrille, and Kalantar-Zadeh, Kourosh

Abstract

Low melting point eutectic systems, such as the eutectic gallium–indium (EGaIn) alloy, offer great potential in the domain of nanometallurgy; however, many of their interfacial behaviors remain to be explored. Here, a compositional change of EGaIn nanoalloys triggered by polydopamine (PDA) coating is demonstrated. Incorporating PDA on the surface of EGaIn nanoalloys renders core–shell nanostructures that accompany Ga–In phase separation within the nanoalloys. The PDA shell keeps depleting the Ga3+from the EGaIn nanoalloys when the synthesis proceeds, leading to a Ga3+-coordinated PDA coating and a smaller nanoalloy. During this process, the eutectic nanoalloys turn into non-eutectic systems that ultimately result in the solidification of In when Ga is fully depleted. The reaction of Ga3+-coordinated PDA-coated nanoalloys with nitrogen dioxide gas is presented as an example for demonstrating the functionality of such hybrid composites. The concept of phase-separating systems, with polymeric reservoirs, may lead to tailored materials and can be explored on a variety of post-transition metals.

The PDA shell keeps depleting the Ga 3+ from the EGaIn nanoalloys when the synthesis proceeds, leading to a Ga 3+ -coordinated PDA coating and a smaller nanoalloy. During this process, the eutectic nanoalloys turn into non-eutectic systems that ultimately result in the solidification of In when Ga is fully depleted. The reaction of Ga 3+ -coordinated PDA-coated nanoalloys with nitrogen dioxide gas is presented as an example for demonstrating the functionality of such hybrid composites.
