In this work, we used different pyrenes derivatives with a carboxylic acid group to modify the surface of carbon nanotubes (CNTs). This non-covalent method of functionalization can improve the dispersion of CNTs in organic solvent without damaging the desired properties of CNTs. Thin films of CNTs functionalized with pyrene derivatives were deposited onto the glass substrate, which in prior, was treated...
In this work, we optimized the method to non-covalently functionalize carbon nanotubes (CNTs) with several pyrenes derivatized with a carboxylic acid group. By employing a facile physisorption-based modification of the CNT surface, it is possible to obtain several favorable results without any substantial damage to the CNT structure. Besides, functionalized CNTs thin films were deposited on glass...
Centrifuge coating was implemented to fabricate nanostructured conductive layers through solution processing at room temperature. This coating procedure allows fast evaporation, thereby fixing the nanomaterials in their dispersed state onto a substrate by the centrifuge action. Material wastes were minimized by mitigating the effects of particle reaggregation. Using this method, we fabricate single-wall...
We have investigated uniform carbon nanotube (CNT) dispersion in a solution and fabrication of CNT thin films on solid surfaces. To prevent bundle formation, we have examined surface modification of both the CNT surfaces and the substrate surfaces. To enhance the interaction between surfaces of the substrate and the CNTs, the substrate surfaces were made hydrophobic, because CNTs are generally hydrophobic...
