New approaches of soft chemistry for preparation of nanostructured multifunctional composite coatings

Vinogradov A.V., Vinogradov V.V., Vinogradov A.V., Vinogradov V.V., Agafonov A.V., Institute of Solution Chemistry RAS, RU

In this work, we have obtained film heterostructures such as MeO/TiO2 possessing high photoactivity by low-temperature sol-gel method. We have succeeded in obtaining photoactive TiO2-based crystalline coatings, FeTiO3 and CoTiO3, without calcination and possessing an [...]

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 [...]

Extremely Stretchable Electrode based on Combination of Inkjet-Printed Silver and Conductive Composite for Stretchable Lighting Applications

Kim D., Kim S., Byun J., Chung S., Kim D., Kim S., Hong Y., Seoul National University, KR

We have studied stretchable electrode based on combination of inkjet-printed silver electrode and conductive composite materials for stretchable lighting device applications. Previous stretchable electrodes were mainly realized by either vacuum deposition or inkjet-printing of conductive [...]

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 [...]

Overcoming the Achilles’ Heel of Processing of Polymer Nanocomposites: Achieving Well-Dispersed Polymer-Graphite, Polymer-Carbon Nanotube, and Polymer-Graphene Nanocomposites with Major Property Enhancements by Solid-State Shear Pulverization

Torkelson J.M., Brunner P.J., Kane N., Northwestern University, US

Polymer nanocomposites, particularly with carbon-based nanofiller, hold promise for large-scale, commercial application of novel materials with enhanced, tunable properties. Unfortunately, a stumbling block in achieving this goal on a commercial scale is the remarkable difficulty [...]

Development of Nanosilica-Thermoset Matrix Resins for Prepreg Composites

Nelson J.M., Hackett S.C., Goetz D.P., Hine A.M., Schultz W.J., 3M, US

A review of the prepreg thermoset matrix resin development activities at 3M and commercial status of these systems will be provided.

Preparation of a new generation porous thermal insulation mass using functional nanomaterials

Ulbikas J., Boženko J., Spirova N., CJSC Modern E-Technologies, LT

In this work silica precursor is graft on nanomaterials via a free-radical reaction. The modified nanomaterials have an - OEt functional group which allows us to intercalate the polymer between the layers of expandable graphite [...]

Effect of γ-ray irradiated MWCNTs on electrical conductivity of a PET/graphite composite for a bipolar plate application

Kim D-H., Son Y., Kongju National University, KR

The effects of a compounding method and γ-ray treated multiwall carbon nanotubes (MWCNTs) on the electrical conductivity of graphite/PET composites were investigated. We found that dispersion of MWCNTs in the PET phase plays a critical [...]

Dielectric performance of Polymer Nanocomposites Synthesized by Atmospheric-pressure Plasma-treated Silica Nanoparticles

Yan W., University of New South Wales, AU

The incorporation of nanoparticles can effectively enhance the dielectric performance of polymers. However, the organic-inorganic incompatibility prevents the nanocomposites from obtaining the desired properties. To overcome this issue, coupling agents have been used to coat [...]

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 [...]
