Photocatalytic Silver/Silver Halide Polymer Nanocomposites

Tate E., Johnston J.H., Victoria University of Wellington, New Zealand, NZ

Recently it has been shown that hybrid silver/silver halide nanoparticles exhibit interesting photocatalytic properties, and are known plasmonic photocatalysts. Enhanced photostability and photocatalysis are observed in the nanoparticles due to the surface plasmon resonance of [...]

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 [...]

Funcional lead-free composite

Teixeira G.F., de Oliveira J.A.M., Zaghete M.A., Longo E., Varela J.A., Chemistry Institute, UNESP- Araraquara, BR

In the work reported here was obtained a lead-free NaNbO3 / PVDF composite, starting from photoluminescent ceramics particles with 1D morphology obtained by microwave-assisted hydrothermal method. Photoluminescence spectrum of the NaNbO3 particles shown emission around [...]

The Rheology and Processing of Carbon Nanotubes for Polymer Composite Applications

Ma A.W.K., University of Connecticut, US

Carbon nanotubes (CNTs) have a diameter on the nanometer scale and a length on the micrometer or even centimeter scale. The high-aspect-ratio (length to diameter ratio) of CNTs offers a unique competitive advantage for using [...]

Manufacturing and Properties of Nanofiber Composites

Yong D-K, Chungnam National University, KR

Recently, a fiber composite for various industrial applications including automotive, aerospace and civil engineering is in the spotlight as a specialized-functional material such as high strength and modulus, high thermal resistance and high elasticity etc. [...]

Viscosity Behavior of Magnetic Nanoparticle Filled Fluids and Impact Resistance of Their Fabric Composites

Lee S-G, Chungnam National University, KR

Ferromagnetic fluid(FMF) and magneto-rheological fluid(MRF) have been prepared from iron oxide and iron alloy nanoparticles, respectively, with a proper fluidic medium. In the FMF, chemically synthesized iron oxide particles having diameters of several nanometers were [...]

Novel Metal-Matrix Composites with Integrally-Bound Nanoscale Carbon

Forrest D.R., Jasiuk I., Brown L., Joyce P., Salamanca-Riba L., Naval Surface Warfare Center, US

Recent advances in nanomanufacturing have made it possible for large amounts (up to 6 wt.%) of nanoscale carbon to be retained as an integral second phase in metals such as aluminum and copper. The carbon [...]

Elastomer composites containing layered fillers and hydroxyapatities

Lipinska M., Pietrasik J., Zaborski M., Masek A., Institute of Polymer and Dye Technology, PL

Traditionally, as a filler of rubber carbon black is used. It is an active filler able to reinforce and improve the properties of finished rubber products. For ecological and economic reasons the research activity is [...]

Near-Infrared Light Induced Mechanical Responses in Single-to-Few Layer Graphene

Loomis J., King B., Panchapakesan B., University of Louisville, US

Layer dependent physical responses of graphene-based polymer composites to near-infrared (NIR) light are reported. Thin film polymer composites were fabricated and compared utilizing both single layer graphene and few layer graphene (~5 layers). NIR-induced axial [...]

Photomechanical Response in Graphene Nanoplatelet Composites

Loomis J., King B., Burkhead T., Xu P., Bessler N., Terentjev E., Panchapakesan B., University of Louisville, US

Large light-induced reversible and elastic responses of graphene nanoplatelet (GNP) polymer composites are reported. Homogeneous mixtures of GNP/polydimethylsiloxane (PDMS) composites (0.1–5 wt%) were prepared and their near-infrared (NIR) mechanical responses studied with increasing pre-strains. Using [...]
