High Strength Metal-Carbon Nanotube Composites

Goyal A., Wiegand D.A., Owens F.J., Iqbal Z., New Jersey Institute of Technology, US

Carbon nanotubes have been extensively investigated for developing polymer matrix nanocomposites and a number of such nanocomposites are already being used in various applications [1, 2]. Metallic composites, particularly those of aluminum, containing carbon nanotubes [...]

Fabrication of Nano-engineered Composites Reinforced with Carbon Nanotubes (CNTs)

Wicks S.S., Yamamoto N., Guzman de Villoria R., Ishiguro K., Cebeci H., Wardle B.L., Massachusetts Institute of Technology, US

Composites, consisting of aligned advanced fibers embedded in epoxy, are common structural materials used in the aerospace industry for their superior strength to weight ratio and their versatility in tailoring specific mechanical properties, among other [...]

Adapting carbon nanotubes for fine composite structures

Shaffer M., Verdejo R., Tran M., Menner A., Bismarck A., Imperial College London, UK

Although encouraging results have been obtained for nanotube-filled polymers, significant improvements over conventional fillers have proved elusive. A critical factor is the reliance on CVD-grown material, which is available in large quantity at reasonable purity, [...]

Halloysite Nanotubes in Polymers

Daly R.C., Fleischer C.A., Wagner A.L., Duffy M., NaturalNano, Inc., US

Halloysite Nanotubes (HNT TM) provide a new avenue for the preparation of nanocomposites. These unique tubes can be dispersed by normal extrusion processes in a variety of polymer melts to produce nanocomposites with unusual physical [...]

Development of nanocomposites with carbon nanotubes in a thermoplastic elastomer matrix

Broza G., Roslaniec Z., Schulte K., Technische Universitaet Hamburg, TUHH, DE

Thermoplastic elastomers (TPEs) have the potential for application as engineering materials because of their novel properties and ease of processing. We have developed a polycondensation process, which allows the manufacturing of polybutylene terephthalate/polyoxytetramethylene (PBT/PTMO) block [...]

Separation Mechanisms for Nanoscale Spheres and Rods in Field-Flow Fractionation (FFF)

Phelan Jr. F.R., Bauer B.J., NIST, US

A Brownian dynamics simulation for modeling the separation of spheres and rodlike particles in field-flow fractionation (FFF) is developed. Modeling of particle elution for spheres from (10 to 1000) nm was examined. The simulation captures [...]

Multi-Functional Carbon Nanotube Based Filtration Material

Cummings A., Seldon Technologies, Inc., US

The very small diameters of carbon nanotubes (CNTs) present relatively low resistance to fluid flow. This, combined with their high surface area, means that highly-efficient, bio-contaminant removals are possible with a thin filtration media possessing [...]
