Ultrathin, patterned, conducting metallic fibers have been extensively studied as building blocks in flexible electronics. However, their scalable processing and attainment of patterns at room temperature is challenging. In this paper, we report on the patterning of ultra-long silver submicron fibers as woven mesh through the process of continuous draw spinning in the presence of ultraviolet (UV) treatment. The silver fibers can be directly intertwined on flexible substrates, such as polyethylene terephthalate (PET) and polyimide (PI). The as obtained silver submicron fiber mesh present excellent photoelectric properties (T = 90%, R = 9 Ω sq⁻¹) and outstanding flexibility and can be easily transferred on other surfaces. To demonstrate its application, flexible electrochromic smart window and infrared stealth film have been prepared.

超薄的，图案化的导电金属纤维已作为柔性电子产品的基础材料进行了广泛的研究。然而，它们在室温下的可缩放处理和图案的获得是具有挑战性的。在本文中，我们报告了在紫外线（UV）处理下，通过连续拉伸纺丝过程将超长银亚微米纤维作为编织网的图案。银纤维可以直接缠绕在柔性基材上，例如聚对苯二甲酸乙二酯（PET）和聚酰亚胺（PI）。所获得的银亚微米纤维网具有优异的光电性能（T  = 90％，R  = 9Ωsq ^-1）和出色的柔韧性，并且可以轻松转移到其他表面上。为了演示其应用，已经准备了柔性电致变色智能窗和红外隐形膜。
