Carbon Nanohorns

Carbon (C) Nanohorns, Single-Walled, Double Walled and Multi-Walled, are black nano scale cylindrical tubes of graphitic carbon which differ from nanotubes in their "horn-like" shape similar to a sewing thimble giving them numerous applications as both the stiffest and strongest known fibers and because of their unique shape gives them an enormous amount of surface area. The resulting material has found application in proton exchange membrane (PEM) and Polymer Electrolyte (PEFC) fuel cells because they have the duel capability of providing a high surface area conductive layer and open gas paths. They are available in single walled, double walled and multi-walled forms, bundled and unbundled, with tube lengths from 5 to 30 nanometers (nm) and specific surface area (SSA) in the 50 to 500 m²/g range. Carbon Nanohorns are available in ultra high purity and high purity and coated suspended and dispersed forms. Technical support on dispersions and coatings selection is available. Development research is underway in Nano Electronics and Photonics materials, such as MEMS and NEMS, Bio Nano Materials, such as Biomarkers, Bio Diagnostics & Bio Sensors, and Related Nano Materials, for use in Polymers, Textiles, Fuel Cell Layers, Composites and Solar Energy materials. Nanopowders are analyzed for chemical composition by ICP, particle size distribution (PSD) by laser diffraction, and for Specific Surface Area (SSA) by BET multi-point correlation techniques. Novel nanotechnology applications also include Quantum Dots. High surface areas can also be achieved using solutions and using thin film by sputtering targets and evaporation technology using pellets, rod and foil. Applications for Carbon Nanohorns include in fuel cells, flat screen displays, scanning probe microscopes in brushes for commercial electric motors, and in sensing devices and because of their strength in numerous aerospace and automotive uses, in body armor and tear-resistant cloth fibers and textiles and stronger and lighter sports equipment . Carbon nanohorns can behave like a conductive metallic or semiconductor depending on their structure, which is useful for nanoscale electronic devices and in electrically conductive films in coatings, plastics, nanowire, nanofiber and in certain bioscience applications. Carbon Nanohorns are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available.
