Role of Nanoparticles in Life Cycle of Nanocomposites

Gu X., Chen G., Zhao M., Watson S.S., Zhe D., Stutzman P.E., Nguyen T., Chin J.W., Martin J.W., NIST, US

This study is to investigate the role of ZnO nanoparticles in the life cycle of a waterborne polyurethane (PU) nanocomposite during UV exposure. The specimens were exposed to the NIST SPHERE (Simulated Photodegradation via High [...]

Integration of SWCNT into Olefin polymer composites

Guan J., Simard B., National Research Council Canada, CA

Single Walled Carbon NanoTubes (SWCNT) have covalently integrated into polyolefin such as PP and PE. SWCNTs are homogeneously distributed in the polymer matrix without interface problem due to covalently anchor.

Chemical and Phase Transformations of Nanocrystalline Oxides in a Carbon Nanoreactor

Volodin A.M., Zaikovskii V.I., Bedilo A.F., Klabunde K.J., Boreskov Institute of Catalysis, RU

The application of nanocrystalline oxides as precursors for synthesis of new nanomaterials with the preservation of the dimensions of the initial nanoparticles is of considerable interest. Its main problem is the sintering and growth of [...]

Surface Modification and Performance Analysis of Jute Based Nanophased Green Composite

Hossain M.K., Dewan M.W., Hosur M., Jeelani S., Rangari V., Tuskegee University, US

The surface modification of jute fibers was accomplished by performing subsequent chemical treatments such as detergent washing, dewaxing, alkali and acetic acid treatment. The morphology of the modified surface was examined using the scanning electron [...]

Properties of a Newly Developed Carbon-Aluminum Nanocomposite

Yang M., Novak J., Fink R., Brookover J., Jiang N., Applied Nanotech, Inc., US

A unique carbon-based metal nanocomposite comprised of 80% carbonaceous matrix and a dispersed metal component of 20% aluminum material, represents a culmination of efforts in material science and manufacturing processes focused on the advancement of [...]

Permittivity of BaTiO3 polymer composite with differing particle size distribution

Schumacher B., Geßwein H., Hanemann T., Haußelt J., Forschungszentrum Karlsruhe GmbH, DE

In previous works the authors presented the possibility to raise the permittivity of polyester-reactive-resin composite materials by using thermal treatment steps to optimize the crystal structure of a nano-powder before incorporating it into the composite. [...]

Rheology, Microstructure, and Property of Polylactide/Clay Nanocomposites Prepared with SC-CO2 by Melt Compounding

Jiang G., Chen Z.K., Huang H.X., South China University of Technology, CN

The rheology, microstructure and mechanical properties of polylactide (PLA)/clay nanocomposites were investigated. The nanocomposites were prepared using a twin screw extruder with and without the aid of supercritical carbon dioxide. Results show that there exists [...]

Using Nanoparticles and Carbon Nanotubes to Enhance the Properties of a Lead-free Solder

Nai S.M.L., Han Y.D., Jing H.Y., Tan C.M., Wei J., Gupta M., Singapore Institute of Manufacturing Technology, SG

Solders are used in various levels of electronic assembly sequence, whereby good electrical, thermal and mechanical performances of solder are necessary. With miniaturization of devices, diverse functional requirements and ever-stricter operating environments of devices, the [...]

Nano-Engineered Dielectrics for Energy Storage Solutions

Badi N., Bensaoula A., University of Houston, US

We present a novel laser processing technique to produce nanodielectric films, which are based on polymer coated metal nanoparticles. The polymer-coated Au NP composite was spin-coated onto a nickel foil serving as the bottom electrode [...]
