具有并入的纳米颗粒的石墨烯涂覆的织物可以是用于多种应用的智能纺织品。棉织物表面含氧官能团的存在使其更适合于改性和功能化。在这里，我们报告了通过确保石墨烯表面棉和纳米颗粒之间的强键合来合成具有优异洗涤耐久性的还原氧化石墨烯（RGO）涂覆的铜（Cu）/银（Ag）纳米颗粒并入的棉织物。在我们的程序中，在棉织物上涂覆氧化石墨烯（GO）之后，使用3-缩水甘油氧基丙基三甲氧基硅烷作为偶联剂通过浸涂方法并入Cu/Ag纳米颗粒。此外，在连二亚硫酸钠的存在下还原GO，然后在真空下在180 °C下加热。RGO涂覆的和Cu/Ag掺入的棉织物样品表现出比纯棉改善的疏水性。与Cotton-RGO-Ag和仅Cotton-RGO相比，Cotton-RGO-Cu显示出显著更低的表面电阻（6.42 KΩ/sq）、更好的UV防护因子（46.45）和焦耳加热能力。此外，棉-RGO-Cu在20次洗涤循环后保持其16.70 KΩ/sq的电阻。总的来说，增强的疏水性、高紫外线防护性、低表面电阻和热稳定性的协同影响使得Cotton-RGO-Cu织物适用于智能纺织品和防护服。
Graphene coated fabrics with incorporated nanoparticles can be smart textiles for multiple applications. The presence of an ample amount of oxygen-bearing functional groups on the surface can make the cotton fabric more suitable for modifications and functionalization. Here, we report the synthesis of reduced graphene oxide (RGO) coated-copper (Cu)/silver (Ag) nanoparticle incorporated cotton fabrics with excellent washing durability by ensuring strong bonding among graphene surface-cotton and nanoparticles. In our procedure, graphene oxide (GO) coating on the cotton fabric was followed by the incorporation of Cu/Ag nanoparticles via dip-coating approach using 3-glycidyloxypropyl trimethoxy silane as a coupling agent. Furthermore, the GO was reduced in the presence of sodium dithionite followed by heating at 180 °C under vacuum. The RGO coated and Cu/Ag incorporated cotton fabric samples exhibited improved hydrophobicity than pure cotton. Cotton-RGO-Cu showed remarkably lower surface resistance (6.42 KΩ/sq), better UV protection factor (46.45), and Joule heating capability as compared to Cotton-RGO-Ag and only Cotton-RGO. Moreover, the Cotton-RGO-Cu retained its resistance of 16.70 KΩ/sq after 20 wash cycles. Overall, the synergetic impact of enhanced hydrophobicity, high UV protectivity, low surface resistance, and thermal stability, have made the Cotton-RGO-Cu fabric suitable for smart textile and protective clothing.
