“…The original PET fabrics show four significant peaks at 14.0°, 17.5°, 22.7°, and 25.5° (Figure 8a), corresponding to four crystal planes of (011), (010), (110), and (100), respectively (Joint Committee on Powder Diffraction Standards, JCPDS card No. 00-050-2275) [28]. The PDA/PET fabrics show a similar XRD pattern, indicating that the PDA coating has little influence on the crystalline structure of PET fabrics (Figure 8b).…”

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 Escherichia coli 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.

“…Different methods have been used to improve the electrical conductivity and electromagnetic radiation resistance of textiles, such as embedded conductive fibers [1] or conductive yarns [2] in fabrics, and coated conductive layers on the surface of fabrics [3]. These methods improved the electrical conductivity of textiles while achieving electromagnetic shielding of textiles by absorbing or reflecting electromagnetic waves [4].…”

The commonly used preparation methods of polypropylene functionalization require special equipment to be put into use or take a long time, which limits its application. Therefore, a simple and economical method for preparing silver functionalized nonwoven polypropylene membrane was studied herein. Triethanolamine was first coated on the surface of the polypropylene, and then Ag was deposited on the surface of polypropylene using a continuous reduction reaction of triethanolamine and silver ions. Surface morphology, crystal structure, and surface chemistry during the preparation of Ag functionalized nonwoven polypropylene were investigated. The electrical conductivity, electromagnetic shielding properties, and washing durability of the treated nonwoven polypropylene were also studied. It was found that Ag was uniformly deposited on the surface of the nonwoven polypropylene, and the coating reaction did not change the chemical structure of the polypropylene. The crystallinity and thermal stability of polypropylene were improved after silver coated polypropylene. The washing experiment results showed that the weight gain rate of the treated nonwoven relative to the untreated sample after the 90 min washing ranged from 6.72% to 9.64%. The resistance test results showed that the maximum surface resistivity of Ag coated nonwoven polypropylene was about 1.95 × 105 Ω, which was 64,615 times lower than the original. In addition, the results showed that the maximum electromagnetic shielding effectiveness of the Ag coated nonwoven polypropylene was about 71.6 dB, showing a very good electromagnetic shielding effect.

“…Moreover, the peak intensity became weak after the sputtering and there is no new peak appeared in the FTIR of AGPP when compared with GPP. These results proved that the deposition of AgNPs on GPP did not affect the chemical structure of GPP [49], and Ag film was covered the surface of GPP based on the FTIR and EDX results.…”

Polyethylene/polyethylene terephthalate (PE/PET) nonwoven fabrics were first modified with a continuous graphene layer by using a dipping process, and then deposited with silver nanoparticles (AgNPs) by using magnetron sputtering, and that is a novel method called two-step method. Graphene/PE/PET (GPP) and AgNPs sputtered GPP (AGPP) were prepared to investigate the modification processes on the electrical conductivity of the nonwoven fabrics. The influence of the surface modification by silane coupling agent (KH-560) on the durability of conductive PE/PET composited fabrics is also studied. Surface morphology, chemical structure, thermal stability, electrical conductive and ultraviolet protection properties of the composite fabrics were investigated. The results indicated KH-560 treatment can obviously improve the interfacial adhesion between the graphene and PE/PET then contributes to the enhanced conductive durability of the composite fabrics. The combination of graphene and AgNPs provided more opportunities for the charge transfer paths of AGPP, leading to an improved conductive network and an increased electrical conductivity. In addition, graphene and AgNPs gave GPP and AGPP excellent thermal stability. The research exhibited the advantages of the two-step method, and also indicated AGPP has a promising application for the preparation of wearable electronics.
