Scalable Manufacturing of High-Nanotube-Content Nanocomposite Fabrics

Martinez-Rubi Y., Jakubinek M.B., Ashrafi B., Simard B., Kingston C.T., Palumbo G., McCrea J., Pallotta R., Katugaha H., National Research Council Canada, CA

Carbon nanotubes (CNTs) have long been considered promising for development of advanced composite materials, due to their unsurpassed properties along with low density, and they are now appearing in an increasing number of industrial applications [...]

Functionalized Boron Nitride Nanotubes and their Polymer Nanocomposites

Guan J., Derdouri A., Ashrafi B., Benhalima A., Kim K.S., Kingston C.T., Simard B., National Research Council Canada, CA

Carbon nanotubes (CNTs) integrated polymer nanocomposites demonstrated promising trends to replace traditional metal materials for lightweighting applications. Similarly, boron nitride nanotubes (BNNTs), which are structurally analogous to CNTs, possess complimentary properties, including the optical transparency, [...]

Development and Characterization of Commercial Boron Nitride Nanotube Product Forms

Jakubinek M.B., Martinez-Rubi Y., Kim K.S., Jakubek Z.J., Homenick C.M., Zou S., Klug D., Ashrafi B., Guan J., Walker S., Daroszewska M., Kingston C.T., Simard B., National Research Council Canada, CA

Boron nitride nanotubes (BNNTs) are structurally analogous to carbon nanotubes (CNTs) and possess equally impressive mechanical properties along with a different set of multifunctional properties including higher thermal stability than CNTs, wide band gap, electrical [...]

Polymer Nanocomposites Incorporating Boron Nitride Nanotubes

Jakubinek M.B., Martinez-Rubi Y., Ashrafi B., Guan J., Kim K.S., O’Neill K., Kingston C.T., Simard B., National Research Council Canada, CA

Boron nitride nanotubes (BNNTs) are structurally analogous to carbon nanotubes (CNTs) and possess equally impressive mechanical properties along with a different set of multifunctional properties including higher thermal stability than CNTs, wide band gap, electrical [...]

Cross-Linked Single-Walled Carbon Nanotube Buckypapers and their Composites

Guan J., Jakubinek M.B., Ashrafi B., Johnson M., White M.A., Simard B., National Research Council Canada, CA

Single-walled carbon nanotubes (SWCNT) covalently modified with OH functional groups were assembled into buckypapers through solvent dispersion and vacuum filtration. These SWCNT-OH buckypapers were subsequently crosslinked by wetting with bifunctional linkers followed by hot compression, [...]

Trifunctional Epoxy – SWNTs Composites. a New Non – Covalent SWNTs Integration Approach

González-Domínguez J.M., Ansón-Casaos A., Díez-Pascual A.M., Ashrafi B., Naffakh M., Johnston A., Gómez M.A., Martínez M.T., Instituto de Carboquimica (CSIC), ES

Properly dispersing CNTs within polymers, specifically egarding epoxy matrices, is extremely difficult. A novel non-covalent functionalization technique, in which a block copolymer (Pluronic F68) is used to wrap SWNTs, has been developed combining both concepts: [...]
