Laser-induced synthesis of hybrid C-Au-Ag nanostructures: nanoparticles, nanoflakes, nanoflowers

Manshina A., Povolotskiy A., Povolotskaya A., Koshevoy I., Tunik S., St. Petersburg State University, RU

Metallic silver-gold nanoparticles (1–5 nm) encapsulated into carbon nanospheres (20–30 nm), or carbon flakes and flowers were synthesized via laser-induced chemical liquid phase deposition. The obtained carbon-silver-gold nanostructures are characterized by high specific surface area [...]

Composite of silver nanoparticles in glass nanofibers produced by Laser Spinning

Cabal B., Quintero F., Díaz L.A., Rojo F., Dieste O., Pou J., Torrecillas R., Moya J.S., University of Vigo, ES

In this work we present a new approach to produce a nanocomposite made of non-woven silicate glass fibers containing silver nanoparticles. The process first involves the synthesis of pellets of a soda-lime silicate glass containing [...]

Novel Aluminum-CNT composites for structural applications

Esawi A.M.K., Salama E., The American University in Cairo, EG

The latest enhancements in the mechanical behaviour of Al-CNT composites achieved by the research group are presented : an increase in tensile strength, indentation hardness and Young’s modulus of 69%, 72% and 23%, respectively. The [...]

Flame retardant Polypropylene nanocomposites: Catalytic and synergistic effects between maleic anhydride grafted Polypropylene and cobalt nanoparticles

He Q., Lamar University, US

A novel function of polypropylene grafted with maleic anhydride (PP-g-MA) as synergistic additive to eﬀectively reduce the flammability of polypropylene (PP) nanocomposites (PNCs)reinforced with in situ synthesized cobalt (Co)–cobalt oxide core–shell nanoparticles (NPs) was reported.

Using Magnetic Impact Coating Technique to Prepare Carbon Nanotube-Reinforced Polymer Nanocomposites

Narh K.A., New Jersey Institute of Technology, US

The combination of high aspect ratio, small size, very low density, and more importantly, excellent physical properties, such as extremely high mechanical strength and stiffness, high electrical and thermal conductivity, make carbon nanotubes (CNTs) perfect [...]

Scale-up of Novel Gold Nanoparticle-Wool Fiber Composites: A Commercialisation Success Story

Nilsson T.W., Johnston J.H., Victoria University of Wellington and MacDiarmid Institute of Advanced Materials and Nanotechnology, NZ

The development of novel nanocomposites of metal nanoparticles and natural fibers has allowed the engineering of flexible materials with the desirable properties of metal nanoparticles for numerous applications. One class of novel nanocomposites uses gold [...]

New Generation Nanogold and Nanosilver Polymer Composites and Their Applications

Johnston J.H., Parry M., Victoria University of Wellington, NZ

A new generation of nanogold and nanosilver polymer composites with polyurethane and nylon, and nanofunctionalised polyurethane paints, have been developed. This novel nanoscience provides the opportunity to impart new functionality to these polymer substrates for [...]

Fabrication of Thermoplastic Nanocellulose Composite Material

Lim D.-Y., Lee J.A., Kim K.-K., Korea Institute of Industrial Technology, KR

Nanocellulose fibers with the average diameter below 100nm were successfully obtained by a high shear microfluidizer as shown in Figure 1. Their large surface area and nano-scale dimensions can lead to the emerging materials for [...]

Sustainable and high-performable nano-structured biopackaging materials

Božič M., Majerič M., Kokol V., University of Maribor, SI

In the contribution, there will be presented few strategies that we have studied recently for producing of highly-performed rigid or flexible biopackaging materials, being fabricated as mono- or even multi-layers coating films from renewable biopolymers [...]

Degradability of polymeric composites (ENR/PLA) from renewable resources

Masek A., Zaborski M., Lodz University of Technology, PL

In our research, we reported on biodegradable composites exhibiting specificity properties by melt blending of polylactide (PLA), one of the commercially available biodegradable material, and epoxidized natural rubber (ENR). Blending of ENR with different types [...]
