摘要
液体电子学有望应用于软机器人、印刷电子学和可愈合电子学。液态导体可以弥补固态电子器件的固有缺陷。镓合金因其固有的流动性、导电性和低毒性,已成为液态电子学的变革性材料。然而,将液态金属或其复合材料雕刻成三维结构是一项具有挑战性的任务。为了解决这个问题,我们在此探讨了金属离子与单宁酸(TA)在液-液界面上的界面化学络合。首先,我们确定了液-液界面上的 MIII -TA 网络可以通过干扰界面膜来构造液中液。液滴的表面覆盖率主要取决于金属离子的浓度、金属离子的氧化状态和周围环境的 pH 值。我们进一步扩展了这一方法,证明了 TA 功能化镓纳米粒子(Ga NPs)也能在过渡金属离子存在的情况下雕刻液滴。最后,我们利用金属-苯酚网络的界面反应和界面排挤作用,获得了一种基于模具的独立三维结构。电导率测量结果表明,这些液体结构可用于低压电子应用,从而为液体电子学打开了一扇大门。
Sculpting Liquid Metal Stabilized Interfaces: A Gateway for Liquid Electronics
Liquid electronics foresee potential applications in soft-robotics, printed electronics, and healable electronics. The intrinsic shortcomings of the solid-state electronics can be offset by liquid conductors. Alloys of gallium have emerged as a transformative material for liquid electronics due to its intrinsic fluidity, conductivity, and low toxicity. However, sculpting liquid metal or its composite into 3D architecture is a challenging task. To tackle the issue, herein, we have explored the interfacial chemistry of metal ions and tannic acid (TA) complexation at liquid-liquid interface. First, we have established that MIII -TA network at liquid-liquid interface could structure liquid in liquid by jamming of the interfacial film. The surface coverage of the droplet largely depends on concentration of metal ions, oxidation state of metal ions and pH of the surrounding environment. Further extending the approach, we have demonstrated that TA functionalized gallium nanoparticles (Ga NPs) are also able to sculpt the liquid droplets in the presence of transition metal ions. Finally, a mold-based free-standing 3D architecture is obtained using the interfacial reaction and interfacial crowding of metal-phenolate network. The conductivity measurement reveals that these liquid constructs can be used for low-voltage electronic application, thus opening a doorway for liquid electronics.
