Résumé

As-synthesized carbon nanotubes (CNTs) comprise impurities (by-product carbonaceous species, metallic catalysts, alumina, etc). Unmodified CNTs are insoluble in most solvents due to the existence of the strong van der Waals interactions that hold them together resulting in bundles. This limits the complete exploitation of unique properties of CNTs.Various methods of CNTs functionalization have been reported to enhance their dispersion in different solvents1. Diazonium chemistry plays a very important role in the context of CNTs solubilization and decoration as it involves simple and very effective methodologies to obtain homogeneous functionalities and provide easy access to different side groups for their modifications. Nanoparticles possess unique optical, magnetic and chemical properties due to their nature and size. They provide large surface area. Their properties are most effective with small particles (< 10-20 nm). It is observed in many cases that these effects disappear essentially for sizes larger than 40-50 nm. Nanocomposites of multi-wall carbon nanotubes (MWCNTs) and metal or metal oxide/hydroxide nanoparticle are expected to have characteristics superior to the individual components. In this work, we have developed a simple and efficient technique using infrared irradiation (IR) to functionalize MWCNTs with mono and tricarboxylic aryl diazonium functions and utilize this functional group to decorate MWCNTs surface with different nanoparticles such as bismuth oxide nanocrystals 2, barium oxide nanoparticles 3, lanthanum hydroxide nanoparticles 4 and maghemite nanocrystals 5. The aim is to control the size, nature, concentration and distribution of the desired nanoparticles on MWCNTs. This method is also applicable to prepare nanocomposites with other nanoparticles (work in progress). Bismuth oxide nanocrystals have been decorated on MWCNTs for the first time. Other nanoparticles decoration was already reported in the literature but in the present case, were decorated using tricarboxylic aryl diazonium functionalized MWCNTs for the first time. Our method of decoration overcomes significantly the most of the limitations reported in the literature. Some of these synthesized nanocomposites have been already applied for biomedical (electrochemical sensor)6, environmental (dye removal) 5 and defense applications (energetic materials) 7.
