Study into the attachment of small and large silanes to carbon nanotube via click chemistry

Abstract

Multi-walled carbon nanotubes (MWCNTs) and other low molecular weight were functionalized with an alkyne group via an urethane bond in an attempt to attach to various azide-functionalized silanes, including polyhedral oligomeric silesquioxane (POSS), via the Cu (I)-catalysed [3+2] Huisgen cycloaddition "click" reaction. FTIR spectroscopy and NMR analysis were utilized to follow the introduction of the alkyne-and azide-groups onto their respective particles, as well as their consumption in the final POSS-MWCNT nanohybrid product. This approach provides a simple and convenient route to effectively functionalize not just silanes and POSS, but also a wide variety of nanoparticles, onto the surface of CNTs.

Bacterial Flagellum versus Carbon Nanotube: A Review Article on the Potential of Bacterial Flagellum as a Sustainable and Green Substance for the Synthesis of Nanotubes

“…Bacterial nanotubes may be used as metals, or as semiconductors often used. Therefore, while these bacterial nanotubes are made from the same graphite layer, their electrical characteristics can differ according to the variations as described, making this a very promising area to explore [41].…”
