Nanohybrid silica/polymer subcritical aerogels

Fidalgo A., Ilharco L.M., Farinha J.P.S., Martinho J.M.G., Centro de Química-Física Molecular, Instituto Superior Técnico, PT

Novel nanohybrid silica/polymer aerogels were produced by the soft sol-gel process, under subcritical conditions. They are hydrophobic, monolithic, and with improved mechanical properties. These materials may well be the answer to low cost-high performance insulators. [...]

Magnetic Dye-Adsorbent Catalyst: A “Core-Shell” Nanocomposite

Shukla S., Varma M.R., Suresh K.G., Warrier K.G.K., Council of Scientific and Industrial Research (CSIR), IN

A magnetic dye-adsorbent catalyst has been developed which is the modification of the conventional magnetic photocatalyst. It consists of a nanocomposite particle having a “core-shell” structure, with a magnetic ceramic particle as a core and [...]

Development of Melt Blown Electrospinning Apparatus of Isotactic Polyproylene

Watanabe K., Lee K.H., Lee Y.J., Nakamura T., Lee K.H., Lee Y.J., Kim B.S., Kim I.S., Kim K.W., Kim B.S., Kim I.S., Kim K.W., Kim B.S., Kim I.S., Kim K.W., Shinshu University, JP

Melt blown electrospinning is a method of combining melt blown with melt electrospinning. In this study, we developed the multi nozzle melt blown electrospinning machine. The significant point of this method is to use air [...]

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 [...]
