Silver (Ag) grid is one of the most competitive alternatives for transparent conductors because of its optical transparency, high conductivity, and cost competitiveness. Although printing, self-assembly, and other combination strategies are widely adopted for the fabrication of Ag grids, the size/morphology accuracy adjustments and structural complexity design in micro/nanodimension are still challenges. Herein, adjustable Ag grid patterns at the micro/nanoscale are obtained by the combination of template printing and self-assembly method. The strategy generates air-filled uniform concave meniscus between silicon pillars helped by coating polymer solutions. The experimental results demonstrate that the concave meniscus’ features strongly influence the stick-slip motion of the triple-phase contact line (TCL), which is the key factor for the construction of different Ag grid patterns, and the morphologies of the patterns affect the application of the Ag grid accordingly. By selection of the surface interaction, the proper Ag grids at the micro/nanoscale have good transmittance (85.3%) and low sheet resistance (7.6 Ω sq⁻¹) on the glass substrate, and Ag grids on polyethylene terephthalate (PET) substrate have also been investigated which are important for its application in flexible transparent electronics.

通过界面相互作用制备银网格

银 (Ag) 网格是透明导体最具竞争力的替代品之一，因为它具有光学透明性、高导电性和成本竞争力。虽然印刷、自组装和其他组合策略被广泛用于Ag网格的制造，但微/纳尺寸的尺寸/形态精度调整和结构复杂性设计仍然是挑战。在此，通过模板印刷和自组装方法相结合，获得了微/纳米级的可调Ag网格图案。该策略通过涂覆聚合物溶液在硅柱之间产生充满空气的均匀凹弯液面。实验结果表明，凹弯月面的特征强烈影响三相接触线（TCL）的粘滑运动，这是构建不同Ag网格图案的关键因素，图案的形态相应影响Ag网格的应用。通过选择表面相互作用，合适的微纳米级Ag网格具有良好的透射率（85.3%）和低的薄层电阻（7.6 Ω sq^-1 ) 在玻璃基板上，以及在聚对苯二甲酸乙二醇酯 (PET) 基板上的 Ag 网格也进行了研究，这对于其在柔性透明电子产品中的应用很重要。
