“…Due to its perfect two-dimensional (2D) lattice structure of sp 2 -bonded carbon atoms, graphene has demonstrated dazzling properties in many areas, such as unprecedented high charge carrier mobility, mechanical robustness, thermal conductivity, and the rest 1 , 2 . The attractive properties of graphene have made them desirable templates for “core–shell” 2D metal/graphene nanocomposites (Au, Ag, Cu, Ni, and Pd, et al), with graphene as the matrix and metal as the outer shell 3 , 4 . This metallization process belongs to a sort of surface modification of graphene, not only add the surface active sites to improve the bonding strength between graphene and other materials (e.g.…”

In this paper, copper deposited graphene was fabricated through electroless plating. A novel and facile pretreatment method is introduced based on ultrasonic treatment with nickel nano-particles as the catalytic core. This method abandons the sensitization and activation process in the traditional pretreatment that reduces the time and economic cost dramatically. The static contact angle was determined by an Olympus BX51M optical microscope. The surface morphology and plating composition were characterized via scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS), the infrared radiation (IR) transmittance spectra of the copper plated graphene were measured by Fourier transform infrared spectroscopy (FTIR), the layer structure was measured by Raman spectrum, the phase identification was identified by X-ray diffraction (XRD), the thermogravimetric analysis (TGA) (Q5000 TA instruments, USA) was carried out to detect the thermal characteristics. The electrical resistivity of copper-plated graphene was performed in an especially designed apparatus. The results show that the surface of graphene is coarsened, and the size is reduced after ultrasonic treatment, which can facilitate the nucleation and fine particle distribution of metal. The electroless plated efficiency of copper of the nickel pretreatment copper-plated graphene is 64.27 wt%, higher than that of generic copper-plated graphene at 58.62 wt%. The resistivity decreases rapidly from 1.69 × 10–2 Ω cm of the original Gr to 0.79 × 10–2 Ω cm of Cu/Ni@Gr due to the large number of fine copper particles scattered around the graphene.

“…1,2 Nickel-based ceramic composite powder refers to a composite ceramic powder formed by coat-ing the surface layer of nickel metal with ceramic powder, which has the properties of the nickel cladding layer and the ceramic core. [3][4][5][6] Alumina has good toughness, high hardness, good oxidation resistance, and high-temperature stability. 7 Alumina is often used as a particle phase to enhance the strength of metal-based materials; however, because alumina is not wettable with metals, problems, such as uneven particle distribution, are encountered, and coating the alumina surface with nickel can promote uniform particle dispersion in the matrix, thereby improving the material properties.…”

This paper proposes a new process route for the preparation of Ni/Al2O3 composite powder through fluidized crystallization granulation–hydrogen reduction and investigates the effects of process feasibility, nickel concentration, nucleation method, and hydrogen reduction on Ni/Al2O3‐coated powder. The decrease in nickel concentration, heterogeneous nucleation, and natural air‐drying properties of precursor particles was beneficial to the formation of a complete and uniform cladding layer, and the increase in hydraulic retention time could improve the thickness of the cladding layer. The optimum process involves a nickel concentration of 50 mg/L; hydraulic residence time of 75 h to ensure heterogeneous nucleation; two‐step hydrogen reduction of precursor particles to obtain a complete and uniform Ni/Al2O3 cladding layer; and a powder surface nickel content of 59.5%.

“…Nickel powder is one of the most significant electromagnetic shielding and wave-absorbing materials used in electronic applications [1,2]. Nickel-coated graphite (Ni/C) powder, which combines the self-lubrication of graphite and the electromagnetic shielding effectiveness of nickel, has been widely applied in paint, print ink, adhesive, conductive rubber, and so on [3]. Despite their good performance, conventional Ni/C powder cannot meet the requirements of some modern applications in harsh environmental conditions such as hot and humid environments because the nickel layer on the outer surface of conductive products suffers from oxidizing, resulting in a sharp decrease in electrical conductivity.…”

Nickel-coated graphite (Ni/C) powder has many applications in diverse areas such as paint, print ink, adhesive, conductive rubber, and so on. To increase its stability in harsh environmental conditions, the electroless plating of silver film on Ni/C via ascorbic acid was studied. A silver layer with a thickness of 2.5 μm was successfully plated on Ni/C powder’s surface with an Ag loading of 44.35 wt.%. Silica gel blended with the Ag/Ni/C powder exhibited much higher conductivity under aging conditions of 85 °C and 85% RH for 1000 h than that with pristine Ni/C powder. Further tests showed that the conductivity of Ag/Ni/C powder remained almost unchanged even in an extremely humid and hot condition for 1000 h. Aging tests were carried out for Ag/Ni/C and Ni/C powders under long-term humid and hot conditions (85 °C, 85% RH), in which Ag/Ni/C samples showed much better electromagnetic shielding performance. Due to the excellent properties and reasonable price, the potential applications of Ag/Ni/C in conductive glue and electromagnetic shielding glue could be expected.
