通过增材制造的金属图案化已经逐步在许多医疗、电子、航空航天和汽车行业中得到广泛应用。虽然之前的努力已经产生了各种有前途的金属图案化策略，但它们的复杂性和高成本限制了它们在快速生产和原型制作中的实际应用。在此，介绍了一种基于阴离子辅助光化学沉积（APD）的一步法金印刷技术，该技术可以在环境条件下直接印刷高导电性的金图案（1.08 × 107 S m-1），而无需后退火处理。独特的是，APD使用特定的离子效应与投影光刻图案Au纳米粒子，同时烧结成可调的多孔金结构。前体油墨中的亲液或离液阴离子对通过在印刷过程中采用一系列不同的离子（包括Cl−离子）来调整印刷图案的形态和电导率的显著影响被呈现。此外，还研究了APD印刷金图形的电阻稳定性和电化学性能。印刷Au电极的高导电性和优异的顺应性被证明在生物医学应用的电生理信号传递和采集中具有可靠的性能。这项工作利用了基于光化学沉积的金属图案化在柔性电子制造中的潜力。
Metal patterning via additive manufacturing has been phasing-in to broad applications in many medical, electronics, aerospace, and automotive industries. While previous efforts have produced various promising metal-patterning strategies, their complexity and high cost have limited their practical application in rapid production and prototyping. Herein, a one-step gold printing technique based on anion-assisted photochemical deposition (APD), which can directly print highly conductive gold patterns (1.08 × 107 S m−1) under ambient conditions without post-annealing treatment, is introduced. Uniquely, the APD uses specific ion effects with projection lithography to pattern Au nanoparticles and simultaneously sinter them into tunable porous gold structures. The significant influence of kosmotropic or chaotropic anions in the precursor ink on tuning the morphologies and conductivities of the printed patterns by employing a series of different ions, including Cl− ions, in the printing process is presented. Additionally, the resistance stabilities and the electrochemical properties of the APD-printed gold patterns are carefully investigated. The high conductivity and excellent conformability of the printed Au electrodes are demonstrated with reliable performance in electrophysiological signal delivery and acquisition for biomedical applications. This work exploits the potential of photochemical-deposition-based metal patterning in flexible electronic manufacturing.
