Novel antibacterial hydrogels based on gelatin/polyvinyl-alcohol and graphene oxide/silver nanoconjugates: formulation, characterization, and preliminary biocompatibility evaluation

“…In contrast, in the case of nanostructured ones, the preferred choices are metallic (e.g., zinc oxide, copper oxide, iron oxide, silver and gold NPs), polymeric nanoparticles (e.g., liposomes, micelles, and dendrimers), and carbonaceous nanomaterials (e.g., graphene, graphene oxide, carbon nanotubes, and carbon dots) [ 16 , 17 ]. For instance, these nanostructured, microstructured, and polymeric materials have a wide variety of engineering applications, including absorbing electromagnetic waves in high frequency (GHz) requiring thin thickness, lightweight, and thermal stability [ 18 ]; coating nanomaterials with enhanced magnetic, optical, electrochemical and mechanical properties to avoid erosion and corrosion [ 19 , 20 ]; nanomaterials that could arrest the problems that affect the efficiency of Li-ion batteries and, improve the storage and delivering capacity for long term cyclability [ 21 ]; and develop potential anode materials for sodium-ion batteries [ 22 ]. Moreover, there are other exciting materials such as complex iron oxides, dielectric oxides, and superconducting oxides.…”

Graphene-Reinforced Zn–Ni Alloy Composite Coating on Iron Substrates by Pulsed Reverse Electrodeposition and Its High Corrosion Resistance

“…Meanwhile, the elastic modulus also increases by 39 and 57%, respectively. The enhancement of Gr on the mechanical properties of the composite coatings was also examined by many other research studies. ,,,, These enhancement mechanisms were ascribed as follows: (1) the Zn–Ni alloy was similar to a metallic solid solution and Ni atoms replaced part of lattice sites of Zn atoms, which resulted in the atomic lattice distortion and hindered the deformation caused by an external force; (2) the Gr-reinforcing phase in the coating increased the nucleation sites for the reduction of metal ions and hindered the grain growth, which resulted in the refinement of grain size and a dense microstructure; (3) the strengthening effects of Gr also included the inhibition of plastic flow due to blocking of the dislocation motion, grain refinement, and inherent high mechanical strength of Gr itself.…”

“…It is well known that Zinc (Zn) and Zn-based alloy coatings, involving zinc–cobalt (Zn–Co), zinc–nickel (Zn–Ni), zinc–chromium (Zn–Cr), zinc–copper (Zn–Cu), and zinc–iron (Zn–Fe), provide economical ways to enhance the anti-corrosion performance of iron and steel, which has been employed in industry widely. − In recent years, in order to enhance the corrosion resistance of thin coatings in harsh environments, many composite coatings have been developed for meeting challenging applications. , As we all know, compared with their bulk materials, nano-sized materials have a significant large surface area to volume ratio and therefore, nanocomposite coatings have been widely explored for applications . Correspondingly, various nanomaterials have been used as reinforcing phases for preparing the composite coatings in the field of electrodeposition, such as zinc–nickel alloy–cerium oxide (Zn–Ni alloy–CeO 2 ), zinc–nickel alloy–aluminum oxide (Zn–Ni alloy–Al 2 O 3 ), zinc–nickel alloy–silicon nitride (Zn–Ni alloy–Si 3 N 4 ), zinc–titanium oxide (Zn–TiO 2 ), zinc–nickel–phosphorus alloy–silicon carbide (Zn–Ni–P alloy–SiC), nickel–phosphorus alloy–tungsten carbide (Ni–P alloy–WC), zinc–nickel alloy–carbon nanotubes (Zn–Ni alloy–CNTs), nickel–reduced graphene oxide (Ni–rGO), and zinc–graphene (Zn–Gr). − …”

Enhancing Surface Roughness and Tensile Strength of Electrodeposited Copper Foils by Composite Additives

“…Metal materials with excellent physical, mechanical, and thermal properties have a wide range of applications in functional–structural materials. [ 1 ] Copper foils play a “neural network” role in electronic equipment communication and signal transmission. [ 2 ] However, the size of traditional metal conductors such as copper and aluminum in the printed circuit board (PCB) has shrunk sharply and signal transmission is concentrated on the surface of the conductors, [ 3 ] resulting in signal transmission failure, breakage, and continuous heating of the PCB.…”

“…Electrodeposition is one of the most important methods for preparing coating materials with excellent thermal, electrical, and mechanical properties. [ 1,6–8 ] The addition of suitable additives to the electrolyte is expected to produce materials with special properties. [ 9,10 ] The additives are a class of reagents, including organic solvents and complex agents.…”
