Ultrasonic-assisted electroless deposition of Ag on PET fabric with low silver content for EMI shielding

Silver loading on poly(ethylene terephthalate) fabrics using silver carbamate via thermal reduction

“…The initial decomposition temperature of the silver plating on the PET fabric was a little higher than that of the original, which means that the silver plating had little effect on the heat-resistant properties of the PET fabric. 29,30 The amount of Ag that was finally retained on the PET surface was provided via TGA analysis and was between 13.10 and 3.52% for the samples treated with 26.07-5.21 wt% silver carbamate solution, as summarized in Table I. Figure 8 shows the high-resolution spectra of the reference PET and silver-coated PET.…”

“…The XPS spectrum of the C1s core-level that was obtained for the two samples was deconvoluted to three peaks with a binding energy of 284.6 eV (C-C or C-H), 286.2 (C-OH) and 288.0 (O-C-O). 30 The highresolution XPS of the C1s core-level obtained for PET/Ag is also decomposed to three peaks with a binding energy (BE) of the same values, as shown in Figure 8(a) and (b). The highresolution spectra for Ag3d of the Ag-modified PET/Ag shows two XPS signals at a BE of 368 and 374 eV with 6.0 eV separations that correspond to the Ag3d5/2 and Ag3d3/2 binding energy of Ag 0 , respectively (Figure 8(a)).…”

A novel preparation of silver-plated polyacrylonitrile fibers functionalized with antibacterial and electromagnetic shielding properties

“…Those electrical conductive fabrics or fibers can be used as electromagnetic interference (EMI) shielding materials or applied in smart clothing [6]. Among them, silver plated fibers [7][8][9] will have antibacterial property besides EMI. Many methods have been done to prepare conductive fibers including conductive paints [10], sputter coating…”

Silver-coated glass fibers prepared by a simple electroless plating technique

“…Up to now, several types of metals, such as silver, copper, and so forth, have been deposited on substrates via electroless plating technique [6][7][8][9][10][11][12][13][14][15][16][17]. Typically, silver/ poly(ethylene terephthalate) (Ag/PET) fabrics have been fabricated using ultrasonic-assisted electroless Ag plating, and found that such fabrics with 6.7 % weight of silver content possess the shielding effectiveness (SE) of 32 dB at frequency ranging from 0.01 MHz to 18 GHz [8].…”

Kim et al [9] electroless deposited copper on polymer substrate, and found that specimens activated using Pd aerosol nanoparticles showed a higher range of SE by about 4-10 dB than those activated by Sn-Pd processes in 2-18 GHz frequencies.…”
