Two different lipophilic guanosine derivatives (LipoGs) have been used for the disaggregation of single walled carbon nanotubes (SWCNTs) in chloroform. UV–vis–NIR spectrophotometry, Raman spectroscopy and NIR-photoluminescence measurements as well as AFM and SEM highlight a well debundling of SWCNTs while fluorescence measurements show the adsorption of LipoGs onto SWCNT surface. The ability of LipoGs...
One conventional and two related gemini surfactants have been used for the preparation of stable single‐walled carbon nanotube (SWNT) aqueous dispersions. The surfactants investigated are able to disperse SWNTs at surfactant/carbon nanotube weight ratios far lower than widely used conventional surfactants. The gemini surfactants investigated demonstrated the ability to solubilize a larger amount of...
The design, synthesis and complete characterization of a smart material composed of single-walled nanotubes functionalized with spiropyran-based photo switchable molecules are reported. The chemical complexity of the system requires the use of a range of complementary techniques in order to provide a complete picture of the composition and performance of the nanomaterial. Thermal gravimetric analysis...
