We report the use of spark generation in an inert gas atmosphere to synthesize carbon-encapsulated metal nanoparticles (CEMNs) in a continuous aerosol manner using a metal (nickel, cobalt, iron)-graphite carbon electrode configuration without the use of a vacuum. The spark-generated particles consisted of CEMNs and carbonaceous aggregated debris. The outer layer of the CEMNs showed parallel fringes (ordered graphitic nanostructures) while the debris consisted of disordered nanostructures. Electron and X-ray diffraction showed that both metal and graphite in the CEMNs were the pure elements except for iron-carbon, which contained a carbide phase. Based on the order of the activation energies for carbon diffusion into a metal: iron-carbon (10.5-16.5 kcal mol(-1)) < cobalt-carbon (34.7 kcal mol(-1)) approximately nickel-carbon (33.0-34.8 kcal mol(-1)), it was concluded that carbide particles form more easily from elemental iron than nickel or cobalt. The metal-to-carbon mass fractions of the spark-generated particles from nickel (anode)-carbon (cathode), cobalt-carbon, and iron-carbon spark configurations were 18.7, 28.3, and 11.2%, respectively, while the mass fractions for the configurations of metal (cathode)-carbon (anode) were 6.4, 9.1, and 4.3%, respectively. Similarly, the yield of CEMNs from the metal (anode)-carbon (cathode) electrodes was higher (54, 61, and 53%) than that of metal (cathode)-carbon (anode) electrodes (18, 30, and 18%).

“…Metallization of polymers has attracted considerable attention and research interest over the past few years. − Aromatic polysulfonamide (PSA) fibers, with a registered trademark of Tanlon, can be selected as substrates because of their outstanding properties such as chemical durability, flame retardancy, high strength, lightweight, and thermal stability. They are the first originally developed aramid fibers with sole intellectual property in China, which have already been widely used in aerospace and military applications such as protective textiles, flue gas filtrations, insulation materials, and reinforcement materials.…”

Silverized aromatic polysulfonamide (PSA) fibers were prepared through a novel chlorine-aided silver activation system followed by electroless nanoplating in the present work. The Ag/AgCl interfacial layer was first introduced to the fiber surface via successive immersion in NaClO-HCl solution, AgNO3 solution, and NaBH4 solution, whose activating and anchoring abilities were then employed to coat an adhesive and uniform silver layer onto PSA fibers by electroless nanoplating. The obtained silverized PSA fibers possessed high electroconductivity, minor paramagnetism, excellent electromagnetic shielding effectiveness, outstanding tensile property, and thermostability, which were also resistant against sonication and exhibited good electroconductivity after exposure in air for half a year. They can act as electromagnetic interference shielding and static charge dissipation materials in coaxial cables and wear protection, which then show a wide application prospect in aerospace, telecommunications, and military industries.

“…Furthermore, as less reactive reductants are used, a lowly adhesive copper film is usually obtained on the surface of the textile. To address this issue, the textile is usually pretreated prior to copper plating by sealing, sandblasting, and etching or by using chemical sensitizers, − plasma, and supercritical carbon oxide. The surface-treated textile can then have improved adhesion strength through enhanced bonding to copper.…”

Throughout history earth-abundant copper has been incorporated into textiles and it still caters to various needs in modern society. In this paper, we present a two-step copper metallization strategy to realize sequentially nondiffusive copper(II) patterning and rapid copper deposition on various textile materials, including cotton, polyester, nylon, and their mixtures. A new, cost-effective formulation is designed to minimize the copper pattern migration on textiles and to achieve user-defined copper patterns. The metallized copper is found to be very adhesive and stable against washing and oxidation. Furthermore, the copper-metallized textile exhibits excellent electrical conductivity that is ~3 times better than that of stainless steel and also inhibits the growth of bacteria effectively. This new copper metallization approach holds great promise as a commercially viable method to metallize an insulating textile, opening up research avenues for wearable electronics and functional garments.
