Here, we report the creation of highly adhesive transparent and stretchable coatings via spray-deposition of solution-based silver nanowires (AgNWs). The AgNW dispersion was spray-deposited on a polydopamine-modified stretchable elastomeric substrate to prepare thin, stretchable, transparent, highly conductive films. The polydopamine layer on the elastomeric substrate created a highly hydrophilic surface, which facilitated the subsequent spraying of the AgNW solution. Additionally, the spray-deposited AgNWs demonstrated excellent adhesion to the substrate, which allowed the fabrication of stretchable electrodes with high conductivity. The AgNW-coated elastomeric substrate exhibited ~80% transmittance with an average sheet resistance of ~35 Ω/□, making it suitable for transparent electrode applications. The conductivity of the transparent electrode was maintained up to ~20% mechanical elongation, which demonstrated the stretchable characteristics of the AgNW-coated elastomeric substrate.
在这里，我们通过喷涂基于溶液的银纳米线 (AgNWs) 来报告高度粘合的透明可拉伸涂层的创建。AgNW 分散体被喷涂在聚多巴胺改性的可拉伸弹性体基底上，以制备薄的、可拉伸的、透明的、高导电的薄膜。弹性体基底上的聚多巴胺层形成了高度亲水的表面，这有助于随后喷涂 AgNW 溶液。此外，喷涂的 AgNW 表现出对基底的优异附着力，这允许制造具有高导电性的可拉伸电极。AgNW 涂层的弹性体基底的透光率约为 80%，平均方阻约为 35 Ω/□，使其适合透明电极应用。透明电极的导电性保持在约 20%的机械伸长率，这展示了 AgNW 涂层的弹性体基底的可拉伸特性。
