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

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, [...]

Integration of SWCNT into Olefin polymer composites

Guan J., Simard B., National Research Council Canada, CA

Single Walled Carbon NanoTubes (SWCNT) have covalently integrated into polyolefin such as PP and PE. SWCNTs are homogeneously distributed in the polymer matrix without interface problem due to covalently anchor.
