摘要
红外超低发射率织物在红外隐身和个人热管理方面的应用引起了人们的极大兴趣。然而,协调低发射率、透气性和机械强度的竞争要求是一个艰巨的挑战。本文提出了一种具有独特非通孔结构的透气性聚合物超织物。这种设计是通过化学镀银纳米粒子到市售尼龙织物上,辅以热加工尼龙多孔网的中间层来实现的。该超织物具有0.044的超低发射率,51 315 S m−1的优异导电性,78 dB的电磁干扰屏蔽效率和110 MPa的高拉伸强度。超织物的发射率、电导率和强度是红外低发射率织物中报道的最高值。超织物的透气性也符合国际二级标准。该超结构通过其被动辐射和主动太阳/焦耳加热的综合能力,促进了不同环境下的个人精确加热。此外,超织物还具有抗菌、阻燃、吸汗、快干和耐洗等性能,从而显著提高了其耐磨性。这种高性能、多功能、红外超低发射率聚合物超织物在红外伪装、电磁防护和个人热管理方面的应用前景广阔。
Infrared ultralow‐emissivity fabric has garnered significant interest for applications in infrared stealth and personal thermal management. However, reconciling the competing demands of low emissivity, breathability, and mechanical strength poses a formidable challenge. Here, an air‐permeable polymeric metafabric distinguished by a unique non‐through‐hole structure is presented. This design is achieved through the electroless plating of silver nanoparticles onto commercially available nylon fabric, supplemented by an intermediate layer of hot‐processed nylon porous mesh. This metafabric demonstrates an ultralow emissivity of 0.044, an exceptional electrical conductivity of 51 315 S m−1, an impressive electromagnetic interference shielding efficiency of 78 dB, and a high tensile strength of 110 MPa. The emissivity, conductivity, and strength of the metafabric are among the highest values reported for infrared low‐emissivity fabrics. The metafabric also exhibits an air permeability that conforms to Grade 2 of international standards. The metafabric facilitates personal precision heating across diverse environments through its integrated capabilities of passive radiative and active solar/Joule heating. Additionally, the metafabric displays antibacterial properties, flame retardancy, sweat absorption, quick‐drying, and washability performance, thereby significantly enhancing its wearability. This high‐performance, multifunctional, infrared ultralow‐emissivity polymeric metafabric holds great promise for applications in infrared camouflage, electromagnetic protection, and personal thermal management.
