New Nanocomposites – Controlled Capture of Nanoparticles in Scrolled Nanosheets

Adireddy S., Yao Y., Vargas J.M., Spinu L., Wiley J.B., University of Neworleans, US

The ability to encapsulate linear nanoparticle chains in scrolled nanosheets is an important advance in the formation of nanocomposites. Recent work in our group resulted in the in situ formation of peapod-like structures based on [...]

Preparation and characterization of new nanocomposites synthesized of Au and Au–Ag bimetallic nanoparticles encapsoulated in functionalized multiwalled carbon nanotubes

Sarlak N., Sameri Z., Meyer T.J., Pourrahim R., Shaabani K., University of North Carolina at Chapel Hill, US

Highly dispersed Au and Au-Ag nanoparticles supported on carbon nanotubes are generated using an easy synthesis. MWCNT was opened and its derivative containing -COOH and -OH functional groups was obtained. Polycondensation of monohydrate citric acid [...]

Influence of Nanoclay’s Incorporation On Mechanical and Thermogravimetric Properties of ER/MWCNT Composites

Stimoniaris A.Z., Zois H., Kanapitsas A., Delides C.G., Technological Educational Institute Of Lamia, GR

In this work polymer nanocomposite systems based on epoxy resin (ER), reinforced with amine-modified multi-walled carbon nanotubes (MWCNTs) and/or nanoclays were studied. Thermogravimetric/Differential Thermal Analysis (TGA/DTA) and Dynamic Mechanical Analysis (DMA) techniques were carried out. [...]

Novel CNT-polymer Nanocomposites used in Oilfield for High Temperature, High Pressure Sealing

Ito M., Schlumberger, JP

A novel sealing system base on MWNT (multiwalletd carbon nanotubes) and polymer nanocomposites was developed for the use in the exploration and development of hotter, deeper reservoirs. Fully dispersed and better bonding are two critical [...]

Modified carbon nanotube & poly (3-hexylthiophene) nanocomposites integrated in quasi solid-state dye synthesized solar cells

Karim M.R., King Saud University, SA

Poly (3-hexylthiophene) (P3HT) and modified (functionalized and silanized) multi wall carbon nanotube (MWNT) nanocomposites have been prepared through in-situ polymerization process in chloroform medium with FeCl3 oxidant at room temperature. The composites (P3HT-MWNT) are characterized [...]

Evaluating safety and stability of CNT nanocomposites exposed to environmental conditions

Orlov A., Ramakrishnan G., Ging J., Hubert A., Feka P., Korach C.S., Stony Brook University, US

There is a growing interest in the development of nanocomposites consisting of organic polymers and various nanomaterials. These materials can provide unique functionalities as compared to unmodified polymers in terms of dielectric behavior, thermal and [...]

Nanocomposites of Nanocrystalline Cellulose for Biosensors Applications

Incani V., Danumah C., Boluk Y., University of Alberta, CA

The development of composite materials is getting increased interest, as they can be a way to achieve adequate sensitivity and stability for biosensors. In this work, we describe the use of a composite material made [...]

Manufacturing Tough Amorphous Thermoplastic-Graphene Nanocomposites

Bandla S., Hanan J.C., Oklahoma State University, US

Nanocomposites have been studied for more than two decades because of their superior performance in comparison with traditional composites. However, few products made using nanocomposites are available commercially. Achieving uniform dispersion in the polymer matrix, [...]
