Abstract

In this study, Cu/Ag/polydopamine (PDA)/polyester (PET) fabrics were fabricated for multi-functional textiles. The PET fabrics were firstly modified by dopamine to form a polydopamine (PDA) layer on the fiber surface, then Ag nanoparticles (Ag NPs) were anchored on fiber surface through chelation between PDA and Ag ions, and the Ag NPs were further used as catalytic seeds for in situ reduction of Cu nanoparticles (Cu NPs). The surface morphology, chemistry, and crystalline structure of the prepared PET fabrics were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD). As expected, Cu NPs were evenly dispersed on the surface of fibers. The Cu/Ag/PDA/PET fabrics showed good antibacterial property against and exhibited excellent electromagnetic interference (EMI) shielding ability. The Cu/Ag/PDA/PET fabrics with high performance antibacterial and EMI shielding properties can be applied as functional protective textiles.

摘要

在本研究中，制备了用于多功能纺织品的铜/银/聚多巴胺（PDA）/聚酯（PET）织物。首先用多巴胺对PET织物进行改性，在纤维表面形成聚多巴胺（PDA）层，然后通过PDA与银离子之间的螯合作用将银纳米颗粒（Ag NPs）锚定在纤维表面，并且将Ag NPs进一步用作原位还原铜纳米颗粒（Cu NPs）的催化种子。通过扫描电子显微镜（SEM）、能量色散X射线光谱（EDS）和X射线衍射（XRD）对制备的PET织物的表面形态、化学性质和晶体结构进行了表征。正如预期的那样，Cu NPs均匀地分散在纤维表面。Cu/Ag/PDA/PET织物对[具体细菌名称未给出]显示出良好的抗菌性能，并表现出优异的电磁干扰（EMI）屏蔽能力。具有高性能抗菌和EMI屏蔽性能的Cu/Ag/PDA/PET织物可作为功能性防护纺织品应用。
