Adsorption of Functionalized Silica Nanoparticles on Swelling Clay Minerals

Pham H-T, Nguyen Q.P., The University of Texas at Austin, US

Successful application of nanoparticles is dependent on understanding the mobility, retention, and transport fate of nanoparticles in natural formations. These aspects are greatly influenced by subsurface environmental conditions such as electrolyte type and concentration, temperature, [...]

Interaction of Surface Modified Silica Nanoparticles with Clay Minerals

Metin C.O., Nguyen Q.P., The University of Texas at Austin, US

The interaction of silica nanoparticles with montmorillonite clay was investigated by visual swelling tests, Fourier Transform Infrared (FTIR), and x-ray diffraction (XRD). The adsorption of silica nanoparticles onto montmorillonite was also studied with a UV-Vis [...]

Clay Polyimide Composite Film with Low CTE and High Water Vapor Barrier Property

Ebina T., Kawasaki K., Nakamura T., Yoshida M., Hayashi H., Hayashizaka N., Yamashita T., Yamamoto T., Misyou D., Bando S., Hayashizaka N., Umeda Y., National Institute of Advanced Industrial Science and Technology, JP

A new clay polymer composite film was prepared by mixing specially processed non-swelling clay and polyimide at an optimal ratio. The newly developed film (80 µm thick) was heat-resistant at 450°C and showed very little [...]

Layered nanocomposites of plate-like particles and polymers

Zhang Y., Evans J.R.G., University College London, UK

Clay-polymer nanocomposites have emerged as a new class of material in recent years because a low addition of clay (<5 wt.%) in a polymer matrix causes significant improvement in material properties. They represent the low [...]

Thermal decomposition behavior of clay-phenolic nanocomposite prepared by in situ polymerization

Periadurai T., Vijayakumar C.T., Balasubramanian M., Indian Institute of Technology Madras, IN

In the present study, a clay-phenolic nanocomposite with 5 wt. % clay was synthesized through in-situ polymerization. X-ray diffraction and transmission electron microscopic studies indicate the formation of nanocomposites. Thermal stability of the phenolic resin [...]

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 [...]

Properties of Paraffin Wax/Montmorillonite Nanocomposite Coatings

Pu G., Wang J., Severtson S.J., University of Minnesota, US

Results are reviewed from a study aimed at enhancing the performance of paraffin wax based materials for barrier coating applications. Nanocomposites prepared by ultrasonic processing from paraffin wax matrices and reinforced with organically modified montmorillonite [...]

Structure Characterization of Nanocomposites by Synchrotron X-ray Rays

Hsiao B.S., Stony Brook University, US

In this talk, we will demonstrate that simultaneous small-angle X-ray scattering (SAXS) and wide-angle X-ray diffraction (WAXD) techniques can contribute significantly to the structural analysis on several length scales in nanocomposites containing a soft matter [...]
