Wearable devices have become an important development direction for future consumer electronics, and films with conductivity, stretchability, and transparency are crucial for achieving wearability. In this article, silver nanowires (AgNWs) with a certain aspect ratio and Al2O3-polyethylene terephthalate films with specific size pit structures were prepared. Uniform coating of the AgNW layer and polydimethylsiloxane transfer were successfully realized. The surface resistance of the final obtained film was 14 Ω/sq with a light transmittance of 50.57%. During repeated deformations, the film conductivity was not significantly reduced, and excellent electrical conductivity was maintained. A relatively complicated flexible AgNW circuit was prepared by adding a patterned mask in the scrape-coating step. This is a low-cost method and can be used to form large films. The final product has excellent conductivity and some transparency and can provide new research directions for flexible electronic devices.

通过有效转移银纳米线制备高导电性和可拉伸薄膜

可穿戴设备已成为未来消费电子的重要发展方向，而具有导电性、拉伸性和透明性的薄膜对于实现可穿戴性至关重要。在本文中，制备了具有一定纵横比的银纳米线（AgNWs）和具有特定尺寸凹坑结构的 Al2O3-聚对苯二甲酸乙二醇酯薄膜。成功实现了 AgNW 层的均匀涂层和聚二甲基硅氧烷转移。最终获得的膜的表面电阻为14Ω/sq，透光率为50.57%。在反复变形过程中，薄膜电导率没有明显降低，保持了良好的导电性。通过在刮涂步骤中添加图案化掩模来制备相对复杂的柔性 AgNW 电路。这是一种低成本的方法，可用于形成大薄膜。最终产品具有优异的导电性和一定的透明度，可为柔性电子器件提供新的研究方向。
