Ag-TiO2 Coated Polyurethane Composite Nanofiber Web for Application in the Protection against Chemical and Biological Warfare Agent

Ryu S.-Y., Choi W.H., Ahn C.H., Kwak S-Y, Seoul National University, KR

Threats of chemical warfare (CW) and biological warfare (BW) agents are serious international problems. It is positively necessary to protect humankind against CW/BW agents. The objective in this work is to develop protective clothing that [...]

Thermomechanical Properties of Epoxy Resin MWCNts Nanocomposites

Kanapitsas A., Zois H., Delides C.G., Technological Educational Institute of Lamia Department of E, GR

The main aim of the present work is to study the mechanical and thermal properties of nanocomposite materials based on epoxy resin (ER) matrix reinforced with multi-walled carbon nanotubes (CNTs). The filler content was systematically [...]

Graphene and polymer composite using easy soluble expanded graphite

Lee J-H., Sungkyunkwan University, KR

ESEG was prepared from a fluorinated graphite intercalation compound (FGIC) - C2F∙nClF3 containing inorganic volatile intercalating agent ClF3. The severe expanded state, together with high specific surface area of the ESEG can give us essential [...]

‘In situ polymerization and composite formation’ (IPCF): An important synthesis route in advanced materials science

Mallick K., Witcomb M.J., Strydom A.M., Mintek, ZA

‘In situ polymerization and composite formation’ (IPCF) types of reactions for the synthesis of ‘metal-polymer composite material’ have a potential advantage in the area of ‘synthetic material science’ since both the polymer and the nanoparticles [...]

Multifunctional Nanocomposite Systems

Das A., Dinglasan J., Loukine N., Anderson D., Vive Nano, CA

A method to produce multifunctional nanocomposite materials is presented. Polymer stabilized nanoparticles (e.g. hydroxides, oxides, metals, salts, etc.) are incorporated into a bulk inorganic matrix (zinc oxide/hydroxide, aluminum oxide/hydroxide, ferric oxide, silica, ceria, etc) through [...]

Preparation, properties and thermal control applications of silica aerogel infiltrated with solid-liquid phase change materials

Xiangfa Z., Hanning X., Jian F., Changrui Z., Yonggang J., HuNan University, CN

In the present work, silica aerogel saturated with erythritol as phase change materials (PCMs) was prepared by melt infiltration. The properties of the composite were determined by scanning electronic microscope (SEM), Fourier transformation infrared spectroscope [...]

Effect of Bimodal Micro-Nano Powder Mixture on the Solids Loading and Pressureless Sintering of Silicon Carbide and Aluminum Nitride

Onbattuvelli V., Purdy G., Ramamoothi S., Atre S.V., Oregon State University, US

Solids loading of around 65 vol.% (against the reported 50 vol.%) and 70 vol.% (against the reported 56 vol.%) were achieved for SiC and AlN feedstocks using bimodal micro-nano (μ/n) powder mixtures, respectively. The injection [...]

Deposition of layered TiO2/N,C-ITO film electrodes for solar hydrogen production via water splitting

Wu K.R., Hung C.H., Yeh C.W., Wang C.C., Cho T.P., National Kaohsiung Marine University, TW

In this study, a nitrogen/carbon-codoped indium tin oxide (N,C-ITO) film is deposited on unheated ITO glass substrate. Thereafter, a titanium dioxide (TiO2) film is grown on the N,C-ITO layer to be a layered TiO2/N,C-ITO (Ti/TO) [...]

Nanogold and Nanosilver Wool: New Products for High Value Fashion Apparel and Functional Textiles

Johnston J., Burridge K., Kelly F., Small A., Victoria University of Wellington, NZ

ORAL We have developed a new proprietary nanotechnology and product suite of high value textiles involving the use of nanogold and nanosilver as colourants and functional components in wool. This innovatively links the high value [...]

The physical properties of zein nanoclay hybrid resin as a base for zein nanoclay films

Luecha J., Sozer N., Kokini J.L., University of Illinois at Urbana-Champaign, US

The waste of petroleum-based packaging materials has become the worldwide major environmental concern. Therefore, the biodegradable materials derived from renewable resources have become under spot light as a potential approach to reduce the packaging material [...]
